                    691:   create libcompat.a (and move daemon to it)
1.255     fefe      692:   add getdelim and getline

1.224     fefe      704: 0.15:
1.225     fefe      705:   vfork sucks.  I reverted to the old behavior where vfork==fork.
1.226     fefe      706:   fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227     fefe      707:   Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall

                    719:   Fix gethostbyname to match host names case insensitively in /etc/hosts.
                    720:     Oops, this was reported 6 weeks ago but I overlooked the email.

                    726:     Make inet_aton use strtoul instead of strtol
                    727:     fdopen would close the file descriptor if it could not malloc the
                    728:       buffer.
                    729:     strftime updates.

                    731:   Andre found a typo in endian.h for big endian mips
1.234     fefe      732:   Ryan told me that fmod was not included in libm.  Oops.
1.235     fefe      733:   strstr(whatever,"") returned NULL, not whatever.  Found by a new test
                    734:     suite entry for strstr that I wrote.
1.245     fefe      735:   Thomas Ogrisegg suggested or sent patches for the following:

1.241     fefe      747:   removed annoying -Wconversion gcc switch
1.242     fefe      748:   add -v to diet.c and fix MIPS CFLAGS in diet.  Thanks, Johannes Stezenbach
1.243     fefe      749:   Kurt Garloff sent these diffs:
                    750:     add fdatasync (and make it a pthread cancellation point)
                    751:     numerous alpha issues, like using .quad instead of .long for
                    752:     offsets, change strip to -strip in Makefile (so a failing strip does
                    753:     not abort the make), try to be more friendly to the gcc 2.96 that
                    754:     SuSE 7.1 AXP ships with.
1.224     fefe      755: 
1.209     fefe      756: 0.14:
1.224     fefe      757:   fix brk again (missing __brk, trivial oversight)
1.210     fefe      758:   a new i386/atol.S that is 4 bytes smaller (and faster, too!).  Thanks,
                    759:     Thomas Ogrisegg!
1.211     fefe      760:   Thomas also contributed a PA-RISC port including testandset, so
                    761:     libpthread will work once we implement clone!  Great work, Thomas.
1.212     fefe      762:   made the fake locale more believable.
                    763:   If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213     fefe      764:   moved _exit into the unified syscall on x86.
1.214     fefe      765:   Uwe Ohse found many more bugs:
                    766:     getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
                    767:     liblatin1 was more or less completely broken if you gave it chars as
                    768:     arguments, not ints (signedness).  execvp had a buffer overflow in
                    769:     case a PATH element exceeded PATH_MAX, but it's not a security
                    770:     problem since setuid programs need to set their path to some known
                    771:     value anyway.
1.219     fefe      772:     hasmntopt did not work with foo=bar style options
1.217     fefe      773:   Uwe also improved ftw's stack usage.
1.214     fefe      774:   Put movl instead of popl rationale in comment in i386/unified.S since
                    775:     three people have suggested saving a few bytes with popl now ;)
1.215     fefe      776:   I discovered __attribute__((malloc)) and started using it.  For gcc 3,
                    777:     it improves the optimizer when functions return malloced pointers.
1.216     fefe      778:   Steven Rostedt pointed out that my setvbuf was broken with regard to
                    779:     size==0 and sent a patch to fix it.
1.218     fefe      780:   Thomas Ogrisegg made setenv smaller.
1.220     olaf      781:   Olaf: implemented the parisc clone and an atomic testandset, modified the
                    782:     libpthread to respect the parisc UPgrowing stack. still non functional,
                    783:     because the unified syscall uses errno :(
1.221     fefe      784:   tcgetospeed read from the wrong termios field.  Thanks, Gunnar Ritter!
1.222     fefe      785:   Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
                    786:     don't write anything which was no longer the case.  It also
                    787:     allocated one byte unnecessarily, which Uwe Ohse found.
1.223     fefe      788:   Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209     fefe      789: 
1.193     fefe      790: 0.13:
1.194     fefe      791:   add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199     fefe      792:   make diet not include the linker safeguard stuff when preprocessing
1.207     fefe      793:   Olaf: port to S/390!

1.199     fefe      796:   diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198     leitner   797:   fixed fflush on input streams (tic from ncurses exposed this)
1.199     fefe      798:   duh, there is an alarm system call, too, so we use it and not setitimer
1.200     fefe      799:   fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201     fefe      800:   rewrote __dtostr (it also has one more argument now)
1.205     fefe      801:   Thanks to Erik Troan for bringing these to my attention:
1.204     fefe      802:     make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
                    803:     fix strncat for the case where n == 0 (security implications?)
                    804:     fix bsearch (it didn't find the very last element in the array, same
                    805:       bug in both the C and the i386 assembly version).
1.205     fefe      806:     fixed FNM_PATHNAME in fnmatch
1.204     fefe      807:   fix brk (the syscall was documented incorrectly in the Linux man page)

1.205     fefe      809:   added negated character classes to fnmatch (not required by POSIX)
1.206     fefe      810:   make the utmp routines open utmp read-only if read-write doesn't work.
1.208     fefe      811:   remove syscalls.c directory, it is obsolete now with unified syscalls
1.193     fefe      812: 
1.164     fefe      813: 0.12:
                    814:   more contributions from Frank Klemm.
1.165     fefe      815:   iconv can now do UCS-2, too.
1.167     fefe      816:   Imported several x86 assembly routines from Wouter van Kleunen.
1.166     fefe      817:   Lots of bug fixes, and several more i386 specific versions of common
                    818:     routines to make them smaller.
1.168     fefe      819:   add memmem (a GNU extension that looks useful)
1.170     fefe      820:   several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168     fefe      821:     add pivot_root syscall, %n for *scanf.
1.169     fefe      822:   add adjtimex (thanks, Laurent BERCOT)
1.171     fefe      823:   add Frank Klemm's optimized md5
1.172     fefe      824:   add -Os option to diet (see diet.1).
1.173     fefe      825:   several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174     fefe      826:   add 32-bit uid/gid syscalls.
1.175     fefe      827:   add rand48 (thanks, Johannes Kloos)

                    831:   fix gethostent alias list termination.  Major oops.
1.178     fefe      832:   add execle and two DNS constants (from Johannes Kloos).

                    837:     If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
                    838:     external reference to a symbol that is only in the diet libc.  So,
                    839:     when you accidentally link a diet libc compiled object file against
                    840:     glibc, the linker will barf.  This will bloat your object files, but
                    841:     you can remove all the references with "strip -R .note" from
                    842:     the binaries in the end (which you should do anyway).
1.182     fefe      843:   fix ARM unified syscall (select did not work).
1.183     fefe      844:   add getpwent_r ala glibc and replace getpwent

                    851:     implementation in the sense that it once worked for Olaf in a clean
                    852:     room ;)

                    855:     longer a line separator but starts a comment, switched to .macro)
1.189     fefe      856:   changed all st_[cma]time types to signed long so comparisons against
                    857:     LONG_MIN will work correctly.  (GNU tar does this)

1.120     fefe      874:   I wrote a new getopt.  It appears to actually work (it is POSIX
                    875:     compliant, it does not sort argv like the GNU version) and is only
                    876:     a little over 300 bytes on x86.
1.121     fefe      877:   Guillaume Cottenceau just wrote me that strncat should be even more
                    878:     broken than it already is: it should append n bytes AND THEN \0!
1.463     leitner   879:     I wonder how many programmers have produced off-by-one errors here...
1.122     fefe      880:   Fix regexec offset return.  autoconf now believes that diet libc has

1.132     olaf      894:   Olaf: added a lot of code in libdl (not yet complete), changed the
                    895:     startup code to make it work with his libdl and ld.so (needs still work
                    896:     too)
1.134     fefe      897:   __dns_readstartfiles only took the first domain or search path.
                    898:     Thanks, Anthony de Boer
1.133     olaf      899:   Olaf: added clone and a new unified_syscall for PowerPC
                    900:     also dynlinker is now available (i386 only at this time)

1.136     fefe      902:   implement getopt_long (ugh, the GNU people need professional help)
1.137     fefe      903:   fixed word delimiters in regex (they looked for space, i.e. "," did
                    904:     not work as delimiter)
1.138     fefe      905:   errno.h now declares sys_errlist and sys_nerr.
1.143     fefe      906:   added mkdtemp.
1.142     fefe      907:   Uwe Ohse reported all of the following bugs:

                    912:     fgetc did not set the internal EOF indicator on EOF.
                    913:     bsearch contained an assumption about integer arithmetic overflow
                    914:       behavior.
                    915:     system did not set SIGCHLD and thus contained a race.
                    916:     popen did not set close-on-exec and could leak an fd on malloc error.
1.147     fefe      917:     daemon did not check whether open returns an fd below 3
                    918:     perror did not save errno.
1.144     olaf      919:   Olaf: Peter Jones reported some problems with perror; strerror had the

                    921:     Peter also posted a patch to atexit/exit. With some modifications it is

1.145     fefe      923:   Unbuffered stdio and ungetc can no longer be disabled.  I will try to

1.102     fefe      993:   wrap getcwd to comply to man page (the syscall returns the number of

1.42      fefe     1039:   added qsort() and bsearch().  Benchmark on 1000 random ints:
                   1040:     glibc: 679414 cycles qsort and 3352 cycles bsearch

1.45      fefe     1047:   corrected __dtostr (it looped when trying to format "0.0").

                   1056:   add isgraph and isxdigit
1.52      fefe     1057:   add strftime (ugh!!!)
1.53      olaf     1058:   Olaf fixed strftime, gmtime_r leap year bug.
1.54      fefe     1059:   Jeff Garzik contributed a spec file.  I put it in contrib and hope
                   1060:     everbody knows what to do with it...
                   1061:   Olaf checked in a ton of libpthread stuff.
1.55      fefe     1062:   added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56      fefe     1063:   add large file backwards compatibility support (so gzip will run on
                   1064:     kernel 2.2 and 2.0)
1.57      fefe     1065:   added shutdown
1.58      fefe     1066:   added nice
                   1067:   added pseudo-locale support for is* (they are now weak aliases,
                   1068:     isupper -> __isupper_ascii etc).  So, for example, liblatin1 can
                   1069:     overwrite the default is* functions.
1.59      fefe     1070:   added liblatin1.a
1.60      fefe     1071:   added tzfile implementation (does it work for anyone else?)
1.668     leitner  1072:   added syslog(3) (thanks to Rene M?ller!)
1.62      fefe     1073:   Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
                   1074:     Thanks!
1.63      fefe     1075:   merged duplicate code in execv and execvp into exec_lib.o
1.34      fefe     1076: 
1.21      fefe     1077: 0.7.2:
                   1078:   added several prototypes to already implemented functions and
                   1079:     <sys/reboot.h>.  Thanks for Abraham for pointing this out.
1.22      fefe     1080:   added prototypes for process group and dup syscalls.  Thanks to
                   1081:     Abraham again.  He also contributed an implementation for daemon(),
                   1082:     an ugly BSD hack.  I decided to diversify the lib/ directory a
                   1083:     little and now created a libugly/ directory for stuff like system()
                   1084:     and daemon() ;-)
                   1085:   added libstdio and moved all that stdio crap from lib/ there.  The
                   1086:     idea is to start separating now what we will separate for shared
                   1087:     libraries anyway.
1.26      fefe     1088:   optimized x86 unified-syscall by Olaf.
1.27      fefe     1089:   added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
                   1090:     limits.h instead)
                   1091:   added remove.c and enough cruft to limits.h to make it compile lzo,
                   1092:     lzop and bzip2.
1.28      fefe     1093:   added mktime, asctime_r, asctime and ctime (needed for gzip).
                   1094:   Someone will need to implement a reader for the glibc localtime file
1.31      fefe     1095:     format some day (man tzfile, ugh!) :-(
1.29      fefe     1096:   added unlink prototype to unistd.h.
                   1097:   added gmtime and gmtime_r.
1.31      fefe     1098:   fixed sparc unified syscall error handling (please upgrade!).
1.30      fefe     1099:   removed readdir glibc compatibility cruft.
1.31      fefe     1100:   removed stat glibc compatibility cruft.
1.32      fefe     1101:   oops, my fread was broken for pipes.
1.33      fefe     1102:   Olaf found a bug in pipe() for sparc, too.
1.21      fefe     1103: 
1.9       fefe     1104: 0.7.1:
1.11      fefe     1105:   optimized away the static arrays from __ltostr and __lltostr.
                   1106:   optimized away the static arrays (and more!) from strtoul and strtoull.
                   1107:   added system (by Olaf).
1.12      fefe     1108:   added tolower and toupper
1.13      fefe     1109:   added getopt from Olaf (~600 bytes on x86!)
1.14      fefe     1110:   added clone for mips (by Olaf).
                   1111:   fixed longjmp and setjmp on sparc not to require glibc include files.
1.15      olaf     1112:   added pause for all (by Olaf).
1.17      fefe     1113:   added __attribute__ ((__const__)) to ctype.h
1.16      fefe     1114:   added isupper and islower.
                   1115:   added putc and putchar as macros.
1.17      fefe     1116:   added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
                   1117:     insightful discussions and patches I partially used for the last three)
1.18      fefe     1118:   added getpriority and setpriority (also by Abraham)
1.19      fefe     1119:   oops, I broke strtoul in a recent optimization attempt.
1.20      fefe     1120:   oi, setjmp and longjmp were broken on other platforms, too!
1.668     leitner  1121:     Thanks to S?bastien C?t? for reporting this.
1.9       fefe     1122: 
                   1123: 0.7:
1.6       olaf     1124:   clone support for i386,alpha,arm and sparc by Olaf.
1.1       cvs      1125:   Initial dynamic loading glue for i386, also by Olaf.
                   1126:   We don't have a dynamic loader yet, so this is not yet usable.
                   1127:   added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
                   1128:     vsprintf, writev, all by Olaf.
1.2       fefe     1129:   imported readdir fix from Guillaume.  Mhh, can the kernel interface
                   1130:     really be this broken?
1.3       fefe     1131:   Found a kludgy way to detect whether the kernel includes define struct
                   1132:     stat64 (they also define STAT64_HAS_BROKEN_ST_INO).  If this does
                   1133:     not work for you, please tell me!
1.4       fefe     1134:   Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7       fefe     1135:   Fixed stdio line buffering.  The code was already there but I forgot
                   1136:     to mark stdio and stdout as line buffered.  This should really be
                   1137:     done dynamically using isatty, though.
1.8       fefe     1138:   Removed superfluous "if (1)" in execvp.c
1.1       cvs      1139: 
                   1140: 0.6.14:
                   1141:   *scanf did not append the 0 byte for %s.
                   1142:   added creat and changed creat to call open directly instead of open64.
                   1143:   did for fread what 0.6.10 did for fwrite.
                   1144:   repaired buffered stdio a little (line buffering is still not
                   1145:     supported).
                   1146:   [All of these bugs have been reported by Guillaume.  Thanks!]
                   1147:   added __pure__ to strchr and strrchr in <string.h>
                   1148: 
                   1149: 0.6.13:
                   1150:   included COPYING to make clear that the diet libc is covered by the
                   1151:     GNU General Public License (and _not_ the LGPL).  That means that
                   1152:     you need to obtain a license from me if you want to use the diet
                   1153:     libc in a proprietary program that you want to distribute.
                   1154:   The x86 unified syscall swapped arguments #4 and #5 and noone
                   1155:     noticed until now!  Thanks to Guillaume Cottenceau for reporting
                   1156:     this!
                   1157:   The malloc had a subtle bug with small allocations that could cause
                   1158:     segfault.  Guillaume reported it, Olaf fixed it.
                   1159: 
                   1160: 0.6.12:
                   1161:   added assert, statfs and fstatfs
                   1162:   added include/net/if.h so fget compiles again.
                   1163: 
                   1164: 0.6.11:
                   1165:   added putenv.
                   1166: 
                   1167: 0.6.10:
                   1168:   fixed fwrite.  It returned the number of bytes written, not the number
                   1169:     of records.  Thanks to Albert D. Cahalan for pointing this out.
                   1170:   fixed fgets.  It returned EOF on empty lines.  Thanks, Erik Frey.
                   1171:   added brk and sbrk.  harold@nb.com.sg made me do it.
                   1172: 
                   1173: 0.6.9:
                   1174:   fixed execvp not to return on ENOENT
                   1175:   did for {open|read|close|seek|tell}dir what I did for stat before.
                   1176:     The glibc compatibility part is currently non-functional.
                   1177:   fixed white space handling in sscanf " (" would not match " (".
                   1178:   fixed printf to accept 'l' flag.
                   1179:   fixed getpwuid (ignored last line)
                   1180: 
                   1181: 0.6.8:
                   1182:   Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
                   1183:     mips and arm.  I did the one for ppc.  They can be enabled in dietfeatures.h.
                   1184:   added strlcpy and strlcat from OpenBSD.
                   1185:   added stat64, fstat64 and lstat64.
                   1186:   added endian.h and made ending of strlen.c endianness-aware
                   1187:   added string routines size tweak to dietfeatures.h.  Most of the
                   1188:     string routines have been unrolled.  This is up to three times as
                   1189:     fast but creates up to three times larger code.  Now you can disable
                   1190:     the unrolling.
                   1191:   added sendfile.
                   1192:   I also added pread.  It works on x86 and sparc but not on ppc and mips.
                   1193:     I have no idea what's going on.  strace disagrees with the kernel.
                   1194:     Can anyone help?  I asked the Linux kernel mailing list for help, too.
                   1195:   added a few aliases of the type __libc_open for open.  nm on
                   1196:     libpthreads.so indicates that we will need them.
                   1197: 
                   1198: 0.6.7:
                   1199:   the sources now compile without warnings with -Wall.
                   1200:   printf now prints "(null)" when %s is passed NULL.  This can be
                   1201:     removed with WANT_NULL_PRINTF in dietfeatures.h
                   1202:   added vfprintf, execl, ttyname.
                   1203:   stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
                   1204:     __dietfstat so they can use the normal kernel struct stat.
                   1205:     stat, lstat and fstat are now C wrappers that convert to the glibc
                   1206:     struct stat.  So we can avoid that overhead for programs that use
                   1207:     dietlibc headers.
                   1208: 
                   1209: 0.6.6:
                   1210:   changed the Makefiles so you can now set CFLAGS on the command line
                   1211:   added memccmp (analogous to memccpy) and strncmp.
                   1212:   Olaf fixed another bug in the sparc unified syscall.
                   1213:   Paul Clifford contributed a C version of his strlen.S that is much
                   1214:     more efficient than the previous strlen on all platforms!  It also
                   1215:     looks like technology from Roswell. ;-}
                   1216:   added a "real" stdio.  Well, almost.  Please contribute!
                   1217:   added dietfeatures.h so you can remove features you don't need.
                   1218:   removed debug code from vsnprintf that changed \0 to ' ' (argh!).
                   1219:   stdio now works with simple programs and minigzip from libz.
                   1220:   stdio uses some major trickery to avoid linking the stdio, stderr and
                   1221:     stdout (and reserving space for them) when they are not used.
                   1222: 
                   1223: 0.6.5:
                   1224:   Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
                   1225:     most of them bugs in the new header files, but also missing sigset
                   1226:     functions.
                   1227:   Paul Clifford contributed an assembly strlen.S for ARM and fixed
                   1228:     several bugs.
                   1229:   Fixed ppc/setjmp and mips/pipe.
                   1230:   Olaf contributed a new sparc unified syscall.
                   1231: 
                   1232: 0.6.4:
                   1233:   declared is* static inline in getservent.
                   1234:   added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
                   1235:   changed strlen to return 0 when passed NULL.
                   1236:   new, much smaller unified syscall for MIPS.  Thanks to Olaf the Mad
                   1237:     Scientist who actually implemented this without access to a MIPS
                   1238:     box, just from reading the architecture manual.  And it worked out
                   1239:     of the box.
                   1240:   started a set of system includes, mainly so that I can use lcc and
                   1241:     my alpha-linux cross compiler (which is unable to cross-compile
                   1242:     glibc).  diet libc can now be compiled without any include files
                   1243:     from a normal libc.  The includes do declare more than diet libc
                   1244:     currently delivers and they are still far from complete for real
                   1245:     applications.
                   1246:   I will only add assembly versions that are smaller _and_ faster than
                   1247:     the C version.  Larger routines are only accepted if they are called
                   1248:     very often and are substantially faster.
                   1249:   added i386 assembly strchr, which is smaller and faster than the old
                   1250:     version.  It is, however, larger than the version contributed by
                   1251:     proton (thanks, anyway).
                   1252:   added i386 strlen (31% faster, 14% smaller)
                   1253:   "make t" will now create a map file called "mapfile".
                   1254: 
                   1255: 0.6.3:
                   1256:   added sys_errlist, strerror and perror
                   1257:   added isblank
                   1258:   added atol
                   1259: 
                   1260: 0.6.2:
                   1261:   mmap for ARM didn't compile.  Thanks, Paul!
                   1262: 
                   1263: 0.6.1:
                   1264:   split mmap into the architecture specific subdirectories.
                   1265:   getenv now copes with environ==NULL, thanks Paul Clifford.
                   1266:   Paul also contributed a smaller ARM startup code.
                   1267: 
                   1268: 0.6:
1.668     leitner  1269:   strcat returned the wrong result.  Thanks, Dietz Pr?pper.
1.1       cvs      1270:   strtod now understands a negative exponent (oops, thanks Bertram Barth)
                   1271:   Port to arm-linux-gnu, but on the Netwinder I use for testing the
                   1272:     __dtostr does not work (I have no idea why!)
                   1273:   The MIPS port now uses (much smaller) non-PIC code.  That means that
                   1274:     the applications you link against diet libc also have to be compiled
                   1275:     non-PIC.  I suggest copying the CFLAGS from the diet libc Makefile.
1.668     leitner  1276:     Thanks to Ralf B?chle for helping me with this!
1.1       cvs      1277:   I made subdirectories for the architectures and use VPATH to override
                   1278:     VPATH so that make finds the source file automatically.  That should
                   1279:     simplify the sources greatly.
                   1280:   Olaf Dreesen contributed Alpha support including setjmp and longjmp!
                   1281:   ARM and MIPS now also have setjmp and longjmp
                   1282:   "compile" and "load" are now make targets.  Use them for djb programs.
                   1283:   added contrib/elftrunc.c which will remove unnecessary ELF headers.
                   1284:     Again, contributed from Olaf.  Great work!
                   1285: 
                   1286: 0.5.12:
                   1287:   printf also does signed numbers.
                   1288:   If you don't use atexit, dietlibc now does not link exit, only _exit.
                   1289:   *printf now correctly returns the number of bytes written.
                   1290:   Olaf contributed experimental sscanf and vsscanf implementations.
                   1291:   If passed NULL as buffer, snprintf will not write anything but still
                   1292:     return the number of bytes it would have written.
                   1293:   Initial MIPS port!   (Oh, the agony!)
                   1294:     No setjmp and longjmp support yet!  Please contribute!
                   1295:   I even implemented unified syscalls for MIPS.  Still, MIPS code is
                   1296:     almost twice the size of SPARC code.  If anyone knows why: please
                   1297:     tell me!
                   1298: 
                   1299: 0.5.11:
                   1300:   I implemented new unified syscalls for x86, sparc and ppc, this time based
                   1301:     on .s files and not .c files, and I moved the syscalls into
                   1302:     subdirectores to clean the dietlibc sources up a little.
                   1303:   A binary consisting of printf("%s is %d\n","olaf",23) is now
                   1304:     2864 bytes on sparc
                   1305:     2488 bytes on intel
                   1306:   I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
                   1307:     to make a few more applications work.
                   1308:   Olaf Dreesen also implemented some unified syscall stuff for x86.
                   1309:   He discovered that with our unified syscall interface it actually
                   1310:     costs <10 bytes total to make all system calls thread safe!
                   1311:   I implemented atexit() (can register up to 4 callbacks).
                   1312:   I implemented strtod and __dtostr (the opposite).  Now we can add
                   1313:     floating point support to vsnprintf and sscanf!
                   1314: 
                   1315: 0.5.10:
                   1316:   I actually saw that I can not only merge the errno handling code of
                   1317:     the system calls on x86, I can also merge the rest (including the
                   1318:     arguments) except for setting the system call number.  All those
                   1319:     system calls are now just a jump to a unified system call handler.
                   1320:     I got rid of x86openclose again.  The savings are substantial:
                   1321:     chown from embutils went from 7664 to 7184 bytes!
                   1322:     If I'd move the system call wrappers to assembly language, I could
                   1323:     even reduce the alignment (does not matter since it's just a jump
                   1324:     anyway) and get rid of the "ret" behind each jump (one byte per
                   1325:     system call!)
                   1326: 
                   1327: 0.5.9:
                   1328:   added memchr, strpbrk, strstr, strtol, isspace (hehe)
                   1329:   fixed strdup
                   1330:   fixed return values for strcpy and strcat (thanks to Norbert Berzen)
                   1331:   Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
                   1332:     (no signed integers, only strings and unsigned integers (but
                   1333:     supporting octal, hex and decimal).  Thanks, Olaf!  (by the way:
                   1334:     that code must be wonderful, I don't understand it at all *bg*)
                   1335:     Olaf's printf does understand padding like in "%08d" and "%8d" and
                   1336:     automatically pads pointers with '0'.
                   1337:   Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
                   1338:   Thanks to proton for inspiration on this.
                   1339:   The new x86 start code also does not reference exit any more, thus saving
                   1340:   64 bytes for executables that don't call exit explicitly.
                   1341:     [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
                   1342:   Moved errno and environ to start.S, saving no byte binary size but
                   1343:     speeding up compilation and slightly shortening dietlibc.a ;-)
                   1344:   For x86: joined open and close into one assembler file, sharing the
                   1345:     errno handling.  This is a feasibility test and it actually saves a
                   1346:     few bytes.  I think I will reimplement the _syscall[1-6] macros on
                   1347:     all platforms now to share the errno handling code for them.
                   1348: 
                   1349: 0.5.8:
                   1350:   fixed strchr to be able to look for 0.
                   1351: 
                   1352:   added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
                   1353:   memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
                   1354:   strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
                   1355:   contributed by Olaf Dreesen)
                   1356: 
                   1357:   added execvp, getcwd
                   1358: 
                   1359:   fixed __xmknod
                   1360: 
                   1361:   Note: can it be that the ftw interface really is so broken that I
                   1362:   cannot implement it without having to implement some searching data
                   1363:   structure?  I included an experimental ftw implementation that will
                   1364:   not follow symlinks.
                   1365: 
                   1366: 0.5.7:
                   1367:   oops, if_nametoindex was broken!
                   1368: 
                   1369: 0.5.6:
                   1370:   ported to ppc-linux.
                   1371:   fixed i386 sigsetjmp (I mistyped the function name)
                   1372:   included sigjmp.c
                   1373: 
                   1374: 0.5.5:
                   1375:   added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
                   1376:   actually, it wasn't fork that wasn't working for sparc, it was pipe.
                   1377:   I fixed it now.
                   1378:   dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
                   1379:   fixed readdir to use getdents and not the intel inline asm
                   1380: 
                   1381: 0.5.4:
                   1382:   ported to sparclinux (sparc32 only).  Beware: does not work yet.
                   1383:   added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
                   1384: 
                   1385: 0.5.3:
                   1386:   added tcsetattr and getenv to compile e3
                   1387: 
                   1388: 0.5.2:
                   1389:   added vhangup, tcgetattr, isatty and memcmp for fgetty
                   1390:     (http://www.fefe.de/fgetty/)
                   1391:   added localtime from uC-libc.
                   1392: 
                   1393: 0.5.1:
                   1394:   stat and friends actually work now.  Yuck!  Another case of
                   1395:     translation between kernel and userland.  Why can't the kernel
                   1396:     people and the libc people simply agree on a standard?
                   1397:   removed many unnecessary includes to speed up compilation.
                   1398:   added -fomit-frame-pointer and i386 compilation target to reduce code size.
                   1399:   inlined socketcall to reduce code size.
                   1400:   "load" and "compile" are examples for djb code.
                   1401: 
                   1402: 0.5:
                   1403:   Olaf Dreesen contributed a much smaller implementation of malloc and friends.
                   1404:   each object file is now treated with "strip -x -R .note -R .comment"
                   1405:   split each system call into a separate object file
                   1406:   added ntohs, htons, alarm, if_indextoname and if_nametoindex
                   1407: 
                   1408: 0.4.1:
                   1409:   oops, the strchr implementation was wrong.  Thanks Jens Laas!
                   1410: 
                   1411: 0.4:
                   1412:   copied opendir and friends from uC-libc.
                   1413:   added getservent and getservby* in gerservent.c
                   1414: 
                   1415: 0.3:
                   1416:   remove readdir system call
                   1417:   added getdents system call
                   1418:   added getpwnam/getpwuid implementation in getpwnam.c
                   1419:   added a few string functions (in str*.c)
