                    568:     offsets, change strip to -strip in Makefile (so a failing strip does
                    569:     not abort the make), try to be more friendly to the gcc 2.96 that
                    570:     SuSE 7.1 AXP ships with.

1.211     fefe      576:   Thomas also contributed a PA-RISC port including testandset, so

1.215     fefe      592:   I discovered __attribute__((malloc)) and started using it.  For gcc 3,

1.216     fefe      594:   Steven Rostedt pointed out that my setvbuf was broken with regard to

                    602:     don't write anything which was no longer the case.  It also
                    603:     allocated one byte unnecessarily, which Uwe Ohse found.
1.223     fefe      604:   Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209     fefe      605:

1.168     fefe      635:   add memmem (a GNU extension that looks useful)
1.170     fefe      636:   several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168     fefe      637:     add pivot_root syscall, %n for *scanf.
1.169     fefe      638:   add adjtimex (thanks, Laurent BERCOT)
1.171     fefe      639:   add Frank Klemm's optimized md5
1.172     fefe      640:   add -Os option to diet (see diet.1).
1.173     fefe      641:   several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174     fefe      642:   add 32-bit uid/gid syscalls.
1.175     fefe      643:   add rand48 (thanks, Johannes Kloos)

                    647:   fix gethostent alias list termination.  Major oops.
1.178     fefe      648:   add execle and two DNS constants (from Johannes Kloos).

                    653:     If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
                    654:     external reference to a symbol that is only in the diet libc.  So,
                    655:     when you accidentally link a diet libc compiled object file against
                    656:     glibc, the linker will barf.  This will bloat your object files, but
                    657:     you can remove all the references with "strip -R .note" from
                    658:     the binaries in the end (which you should do anyway).
1.182     fefe      659:   fix ARM unified syscall (select did not work).

                    662:   remove entlib (new code is smaller)
1.184     fefe      663:   rewrite getserv* to use parselib (and provide ..._r, too)
1.185     fefe      664:   add getpwnam_r and getpwuid_r
1.186     fefe      665:   rewrite getproto* to use parselib (and protive ..._r, too)
1.187     fefe      666:   Olaf muddled with the dynamic linker.  It's a clean-room
                    667:     implementation in the sense that it once worked for Olaf in a clean
                    668:     room ;)
1.188     fefe      669:   add if_nameindex and if_freenameindex.
                    670:   fixed arm unified syscalls to work with current binutils (; is no
                    671:     longer a line separator but starts a comment, switched to .macro)
1.189     fefe      672:   changed all st_[cma]time types to signed long so comparisons against
                    673:     LONG_MIN will work correctly.  (GNU tar does this)
1.190     fefe      674:   fixed two bugs regarding ungetc.
                    675:   add getusershell, setusershell, endusershell (for vs_ftpd)
                    676:   add prctl, dirfd (also for vs_ftpd)
1.191     fefe      677:   fixed strftime (was completely hosed)
1.192     fefe      678:   added real make install target
1.164     fefe      679: 
1.115     fefe      680: 0.11:
                    681:   fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116     fefe      682:   fix vsscanf bug (Thanks, David Chappell).
1.117     fefe      683:   add floor, ceil and memchr prototypes.
                    684:   add __builtin_expect and expect #defines for gcc versions below 3.0

                    686:   add placeholder iconv (iconv_open will always return EINVAL)
                    687:   try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
                    688:     initialization of getaddrinfo.
1.119     fefe      689:   fix vsnprintf %X (printed lower case)
1.120     fefe      690:   I wrote a new getopt.  It appears to actually work (it is POSIX
                    691:     compliant, it does not sort argv like the GNU version) and is only
                    692:     a little over 300 bytes on x86.
1.121     fefe      693:   Guillaume Cottenceau just wrote me that strncat should be even more
                    694:     broken than it already is: it should append n bytes AND THEN \0!
1.463     leitner   695:     I wonder how many programmers have produced off-by-one errors here...
1.122     fefe      696:   Fix regexec offset return.  autoconf now believes that diet libc has
                    697:     POSIX regular expressions.
1.123     fefe      698:   Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124     fefe      699:   Fix regular expression match for x* when there is no x at all.
1.125     fefe      700:   Fix memory leak in error case in gethostbyname(2|).  Thanks, Dietz Pröpper.

1.128     fefe      703:   Make %h work for signed numbers and add %hh to vsnprintf.
                    704:   initgroups ignored the group argument :-(
                    705:   remove printf references and nested functions from glob.
1.129     fefe      706:   added an errno in libpthread that will display a prominent linker
                    707:     warning.
1.131     fefe      708:   started getting rid of kernel headers.  Big task! :-(
1.130     fefe      709:   add res_mkquery.  The diet libc can now compile and link mtr.
1.132     olaf      710:   Olaf: added a lot of code in libdl (not yet complete), changed the
                    711:     startup code to make it work with his libdl and ld.so (needs still work
                    712:     too)
1.134     fefe      713:   __dns_readstartfiles only took the first domain or search path.
                    714:     Thanks, Anthony de Boer
1.133     olaf      715:   Olaf: added clone and a new unified_syscall for PowerPC
                    716:     also dynlinker is now available (i386 only at this time)
1.135     fefe      717:   crufted together a stdarg.h implementation from the various gcc headers.
1.136     fefe      718:   implement getopt_long (ugh, the GNU people need professional help)
1.137     fefe      719:   fixed word delimiters in regex (they looked for space, i.e. "," did
                    720:     not work as delimiter)
1.138     fefe      721:   errno.h now declares sys_errlist and sys_nerr.
1.143     fefe      722:   added mkdtemp.
1.142     fefe      723:   Uwe Ohse reported all of the following bugs:
                    724:     ttyname should return 0 if !isatty.
                    725:     realpath returns NULL if "." cannot be opened
                    726:     putenv erroneously accepted (and mishandled) entries without "=".
                    727:     popen returned 255 instead of 127 if /bin/sh could not be run.
                    728:     fgetc did not set the internal EOF indicator on EOF.
                    729:     bsearch contained an assumption about integer arithmetic overflow
                    730:       behavior.
                    731:     system did not set SIGCHLD and thus contained a race.
                    732:     popen did not set close-on-exec and could leak an fd on malloc error.
1.147     fefe      733:     daemon did not check whether open returns an fd below 3
                    734:     perror did not save errno.
1.144     olaf      735:   Olaf: Peter Jones reported some problems with perror; strerror had the

                    737:     Peter also posted a patch to atexit/exit. With some modifications it is
                    738:     now implemented.
1.145     fefe      739:   Unbuffered stdio and ungetc can no longer be disabled.  I will try to
                    740:     implement part of it using ELF weak symbols.
1.146     fefe      741:   Added minimal sysconf (tehe) from David Chappell.
1.148     fefe      742:   Added overflow handling for strtoul and strtol.
1.149     fefe      743:   Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use

1.150     fefe      745:   Added a littie backwards compatibility cruft for gpm (man, do these

                    761:     legacy <2.2 signal-handling doesn't work at the moment.
1.163     fefe      762:   Made rudimentary iconv that can convert back and forth between
                    763:     iso-8859-1, utf-8 and ucs-4 (for debugging).
                    764:     Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115     fefe      765:

1.76      fefe      770:   add putchar (apparently arm-linux-gcc will substitute printf("\n")

                    808:   my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102     fefe      809:   wrap getcwd to comply to man page (the syscall returns the number of
                    810:     bytes, not the buffer)
                    811:   add realpath.

1.110     fefe      821:   implemented a gross hack to make libpthread compile when
                    822:     dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111     fefe      823:   add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)

1.72      fefe      843:   localtime won't call gettimeofday when the tzfile parser is used.
1.65      fefe      844: 
1.64      fefe      845: 0.8:
1.34      fefe      846:   vsnprintf(0,...) estimated the length of strings with a padding width
                    847:     incorrectly.
1.35      fefe      848:   new reboot() from Olaf.
1.36      fefe      849:   added prototypes for getsockopt and setsockopt.
1.39      fefe      850:   added experimental sem* and shm*
1.38      fefe      851:   define EXIT_SUCCESS and EXIT_FAILURE
1.40      fefe      852:   added setvbuf (only changes mode, not buffer)
1.41      fefe      853:   added dietwarning.h (woohoo, linker warnings!) and used it to warn of
                    854:     insecurity (system, sprintf) or bloat (printf and stdio).
1.42      fefe      855:   added qsort() and bsearch().  Benchmark on 1000 random ints:
                    856:     glibc: 679414 cycles qsort and 3352 cycles bsearch
                    857:     diet libc: 300010 cycles qsort, 553 cycles bsearch
                    858:     I have no idea why glibc is so slow.
1.43      fefe      859:   added __isnan (references by libm.a from glibc).
                    860:   added popen() and pclose().  Now the diet libc can link slsh (from
                    861:     S-Lang!)
1.44      fefe      862:   corrected usleep.  It was more of an msleep until now.
1.45      fefe      863:   corrected __dtostr (it looped when trying to format "0.0").
                    864:   several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46      fefe      865:   added ungetc (does it work?)
1.47      fefe      866:   added inet_aton (yuck!)
1.50      fefe      867:   added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48      fefe      868:   added h_errno and __h_errno_location
                    869:   added inet_ntoa
1.49      fefe      870:   added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51      fefe      871:   add bcopy, index, rindex macros
                    872:   add isgraph and isxdigit
1.52      fefe      873:   add strftime (ugh!!!)
1.53      olaf      874:   Olaf fixed strftime, gmtime_r leap year bug.
1.54      fefe      875:   Jeff Garzik contributed a spec file.  I put it in contrib and hope
                    876:     everbody knows what to do with it...
                    877:   Olaf checked in a ton of libpthread stuff.
1.55      fefe      878:   added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56      fefe      879:   add large file backwards compatibility support (so gzip will run on
                    880:     kernel 2.2 and 2.0)
1.57      fefe      881:   added shutdown
1.58      fefe      882:   added nice
                    883:   added pseudo-locale support for is* (they are now weak aliases,
                    884:     isupper -> __isupper_ascii etc).  So, for example, liblatin1 can
                    885:     overwrite the default is* functions.
1.59      fefe      886:   added liblatin1.a
1.60      fefe      887:   added tzfile implementation (does it work for anyone else?)
1.61      fefe      888:   added syslog(3) (thanks to Rene Müller!)
1.62      fefe      889:   Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
                    890:     Thanks!
1.63      fefe      891:   merged duplicate code in execv and execvp into exec_lib.o
1.34      fefe      892: 
1.21      fefe      893: 0.7.2:
                    894:   added several prototypes to already implemented functions and
                    895:     <sys/reboot.h>.  Thanks for Abraham for pointing this out.
1.22      fefe      896:   added prototypes for process group and dup syscalls.  Thanks to
                    897:     Abraham again.  He also contributed an implementation for daemon(),
                    898:     an ugly BSD hack.  I decided to diversify the lib/ directory a
                    899:     little and now created a libugly/ directory for stuff like system()
                    900:     and daemon() ;-)
                    901:   added libstdio and moved all that stdio crap from lib/ there.  The
                    902:     idea is to start separating now what we will separate for shared
                    903:     libraries anyway.
1.26      fefe      904:   optimized x86 unified-syscall by Olaf.
1.27      fefe      905:   added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
                    906:     limits.h instead)
                    907:   added remove.c and enough cruft to limits.h to make it compile lzo,
                    908:     lzop and bzip2.
1.28      fefe      909:   added mktime, asctime_r, asctime and ctime (needed for gzip).
                    910:   Someone will need to implement a reader for the glibc localtime file
1.31      fefe      911:     format some day (man tzfile, ugh!) :-(
1.29      fefe      912:   added unlink prototype to unistd.h.
                    913:   added gmtime and gmtime_r.
1.31      fefe      914:   fixed sparc unified syscall error handling (please upgrade!).
1.30      fefe      915:   removed readdir glibc compatibility cruft.
1.31      fefe      916:   removed stat glibc compatibility cruft.
1.32      fefe      917:   oops, my fread was broken for pipes.
1.33      fefe      918:   Olaf found a bug in pipe() for sparc, too.
1.21      fefe      919: 
1.9       fefe      920: 0.7.1:
1.11      fefe      921:   optimized away the static arrays from __ltostr and __lltostr.
                    922:   optimized away the static arrays (and more!) from strtoul and strtoull.
                    923:   added system (by Olaf).
1.12      fefe      924:   added tolower and toupper
1.13      fefe      925:   added getopt from Olaf (~600 bytes on x86!)
1.14      fefe      926:   added clone for mips (by Olaf).
                    927:   fixed longjmp and setjmp on sparc not to require glibc include files.
1.15      olaf      928:   added pause for all (by Olaf).
1.17      fefe      929:   added __attribute__ ((__const__)) to ctype.h
1.16      fefe      930:   added isupper and islower.
                    931:   added putc and putchar as macros.
1.17      fefe      932:   added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
                    933:     insightful discussions and patches I partially used for the last three)
1.18      fefe      934:   added getpriority and setpriority (also by Abraham)
1.19      fefe      935:   oops, I broke strtoul in a recent optimization attempt.
1.20      fefe      936:   oi, setjmp and longjmp were broken on other platforms, too!
                    937:     Thanks to Sébastien Côté for reporting this.
1.9       fefe      938: 
                    939: 0.7:
1.6       olaf      940:   clone support for i386,alpha,arm and sparc by Olaf.
1.1       cvs       941:   Initial dynamic loading glue for i386, also by Olaf.
                    942:   We don't have a dynamic loader yet, so this is not yet usable.
                    943:   added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
                    944:     vsprintf, writev, all by Olaf.
1.2       fefe      945:   imported readdir fix from Guillaume.  Mhh, can the kernel interface
                    946:     really be this broken?
1.3       fefe      947:   Found a kludgy way to detect whether the kernel includes define struct
                    948:     stat64 (they also define STAT64_HAS_BROKEN_ST_INO).  If this does
                    949:     not work for you, please tell me!
1.4       fefe      950:   Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7       fefe      951:   Fixed stdio line buffering.  The code was already there but I forgot
                    952:     to mark stdio and stdout as line buffered.  This should really be
                    953:     done dynamically using isatty, though.
1.8       fefe      954:   Removed superfluous "if (1)" in execvp.c
1.1       cvs       955: 
                    956: 0.6.14:
                    957:   *scanf did not append the 0 byte for %s.
                    958:   added creat and changed creat to call open directly instead of open64.
                    959:   did for fread what 0.6.10 did for fwrite.
                    960:   repaired buffered stdio a little (line buffering is still not
                    961:     supported).
                    962:   [All of these bugs have been reported by Guillaume.  Thanks!]
                    963:   added __pure__ to strchr and strrchr in <string.h>
                    964: 
                    965: 0.6.13:
                    966:   included COPYING to make clear that the diet libc is covered by the
                    967:     GNU General Public License (and _not_ the LGPL).  That means that
                    968:     you need to obtain a license from me if you want to use the diet
                    969:     libc in a proprietary program that you want to distribute.
                    970:   The x86 unified syscall swapped arguments #4 and #5 and noone
                    971:     noticed until now!  Thanks to Guillaume Cottenceau for reporting
                    972:     this!
                    973:   The malloc had a subtle bug with small allocations that could cause
                    974:     segfault.  Guillaume reported it, Olaf fixed it.
                    975: 
                    976: 0.6.12:
                    977:   added assert, statfs and fstatfs
                    978:   added include/net/if.h so fget compiles again.
                    979: 
                    980: 0.6.11:
                    981:   added putenv.
                    982: 
                    983: 0.6.10:
                    984:   fixed fwrite.  It returned the number of bytes written, not the number
                    985:     of records.  Thanks to Albert D. Cahalan for pointing this out.
                    986:   fixed fgets.  It returned EOF on empty lines.  Thanks, Erik Frey.
                    987:   added brk and sbrk.  harold@nb.com.sg made me do it.
                    988: 
                    989: 0.6.9:
                    990:   fixed execvp not to return on ENOENT
                    991:   did for {open|read|close|seek|tell}dir what I did for stat before.
                    992:     The glibc compatibility part is currently non-functional.
                    993:   fixed white space handling in sscanf " (" would not match " (".
                    994:   fixed printf to accept 'l' flag.
                    995:   fixed getpwuid (ignored last line)
                    996: 
                    997: 0.6.8:
                    998:   Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
                    999:     mips and arm.  I did the one for ppc.  They can be enabled in dietfeatures.h.
                   1000:   added strlcpy and strlcat from OpenBSD.
                   1001:   added stat64, fstat64 and lstat64.
                   1002:   added endian.h and made ending of strlen.c endianness-aware
                   1003:   added string routines size tweak to dietfeatures.h.  Most of the
                   1004:     string routines have been unrolled.  This is up to three times as
                   1005:     fast but creates up to three times larger code.  Now you can disable
                   1006:     the unrolling.
                   1007:   added sendfile.
                   1008:   I also added pread.  It works on x86 and sparc but not on ppc and mips.
                   1009:     I have no idea what's going on.  strace disagrees with the kernel.
                   1010:     Can anyone help?  I asked the Linux kernel mailing list for help, too.
                   1011:   added a few aliases of the type __libc_open for open.  nm on
                   1012:     libpthreads.so indicates that we will need them.
                   1013: 
                   1014: 0.6.7:
                   1015:   the sources now compile without warnings with -Wall.
                   1016:   printf now prints "(null)" when %s is passed NULL.  This can be
                   1017:     removed with WANT_NULL_PRINTF in dietfeatures.h
                   1018:   added vfprintf, execl, ttyname.
                   1019:   stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
                   1020:     __dietfstat so they can use the normal kernel struct stat.
                   1021:     stat, lstat and fstat are now C wrappers that convert to the glibc
                   1022:     struct stat.  So we can avoid that overhead for programs that use
                   1023:     dietlibc headers.
                   1024: 
                   1025: 0.6.6:
                   1026:   changed the Makefiles so you can now set CFLAGS on the command line
                   1027:   added memccmp (analogous to memccpy) and strncmp.
                   1028:   Olaf fixed another bug in the sparc unified syscall.
                   1029:   Paul Clifford contributed a C version of his strlen.S that is much
                   1030:     more efficient than the previous strlen on all platforms!  It also
                   1031:     looks like technology from Roswell. ;-}
                   1032:   added a "real" stdio.  Well, almost.  Please contribute!
                   1033:   added dietfeatures.h so you can remove features you don't need.
                   1034:   removed debug code from vsnprintf that changed \0 to ' ' (argh!).
                   1035:   stdio now works with simple programs and minigzip from libz.
                   1036:   stdio uses some major trickery to avoid linking the stdio, stderr and
                   1037:     stdout (and reserving space for them) when they are not used.
                   1038: 
                   1039: 0.6.5:
                   1040:   Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
                   1041:     most of them bugs in the new header files, but also missing sigset
                   1042:     functions.
                   1043:   Paul Clifford contributed an assembly strlen.S for ARM and fixed
                   1044:     several bugs.
                   1045:   Fixed ppc/setjmp and mips/pipe.
                   1046:   Olaf contributed a new sparc unified syscall.
                   1047: 
                   1048: 0.6.4:
                   1049:   declared is* static inline in getservent.
                   1050:   added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
                   1051:   changed strlen to return 0 when passed NULL.
                   1052:   new, much smaller unified syscall for MIPS.  Thanks to Olaf the Mad
                   1053:     Scientist who actually implemented this without access to a MIPS
                   1054:     box, just from reading the architecture manual.  And it worked out
                   1055:     of the box.
                   1056:   started a set of system includes, mainly so that I can use lcc and
                   1057:     my alpha-linux cross compiler (which is unable to cross-compile
                   1058:     glibc).  diet libc can now be compiled without any include files
                   1059:     from a normal libc.  The includes do declare more than diet libc
                   1060:     currently delivers and they are still far from complete for real
                   1061:     applications.
                   1062:   I will only add assembly versions that are smaller _and_ faster than
                   1063:     the C version.  Larger routines are only accepted if they are called
                   1064:     very often and are substantially faster.
                   1065:   added i386 assembly strchr, which is smaller and faster than the old
                   1066:     version.  It is, however, larger than the version contributed by
                   1067:     proton (thanks, anyway).
                   1068:   added i386 strlen (31% faster, 14% smaller)
                   1069:   "make t" will now create a map file called "mapfile".
                   1070: 
                   1071: 0.6.3:
                   1072:   added sys_errlist, strerror and perror
                   1073:   added isblank
                   1074:   added atol
                   1075: 
                   1076: 0.6.2:
                   1077:   mmap for ARM didn't compile.  Thanks, Paul!
                   1078: 
                   1079: 0.6.1:
                   1080:   split mmap into the architecture specific subdirectories.
                   1081:   getenv now copes with environ==NULL, thanks Paul Clifford.
                   1082:   Paul also contributed a smaller ARM startup code.
                   1083: 
                   1084: 0.6:
                   1085:   strcat returned the wrong result.  Thanks, Dietz Pröpper.
                   1086:   strtod now understands a negative exponent (oops, thanks Bertram Barth)
                   1087:   Port to arm-linux-gnu, but on the Netwinder I use for testing the
                   1088:     __dtostr does not work (I have no idea why!)
                   1089:   The MIPS port now uses (much smaller) non-PIC code.  That means that
                   1090:     the applications you link against diet libc also have to be compiled
                   1091:     non-PIC.  I suggest copying the CFLAGS from the diet libc Makefile.
                   1092:     Thanks to Ralf Bächle for helping me with this!
                   1093:   I made subdirectories for the architectures and use VPATH to override
                   1094:     VPATH so that make finds the source file automatically.  That should
                   1095:     simplify the sources greatly.
                   1096:   Olaf Dreesen contributed Alpha support including setjmp and longjmp!
                   1097:   ARM and MIPS now also have setjmp and longjmp
                   1098:   "compile" and "load" are now make targets.  Use them for djb programs.
                   1099:   added contrib/elftrunc.c which will remove unnecessary ELF headers.
                   1100:     Again, contributed from Olaf.  Great work!
                   1101: 
                   1102: 0.5.12:
                   1103:   printf also does signed numbers.
                   1104:   If you don't use atexit, dietlibc now does not link exit, only _exit.
                   1105:   *printf now correctly returns the number of bytes written.
                   1106:   Olaf contributed experimental sscanf and vsscanf implementations.
                   1107:   If passed NULL as buffer, snprintf will not write anything but still
                   1108:     return the number of bytes it would have written.
                   1109:   Initial MIPS port!   (Oh, the agony!)
                   1110:     No setjmp and longjmp support yet!  Please contribute!
                   1111:   I even implemented unified syscalls for MIPS.  Still, MIPS code is
                   1112:     almost twice the size of SPARC code.  If anyone knows why: please
                   1113:     tell me!
                   1114: 
                   1115: 0.5.11:
                   1116:   I implemented new unified syscalls for x86, sparc and ppc, this time based
                   1117:     on .s files and not .c files, and I moved the syscalls into
                   1118:     subdirectores to clean the dietlibc sources up a little.
                   1119:   A binary consisting of printf("%s is %d\n","olaf",23) is now
                   1120:     2864 bytes on sparc
                   1121:     2488 bytes on intel
                   1122:   I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
                   1123:     to make a few more applications work.
                   1124:   Olaf Dreesen also implemented some unified syscall stuff for x86.
                   1125:   He discovered that with our unified syscall interface it actually
                   1126:     costs <10 bytes total to make all system calls thread safe!
                   1127:   I implemented atexit() (can register up to 4 callbacks).
                   1128:   I implemented strtod and __dtostr (the opposite).  Now we can add
                   1129:     floating point support to vsnprintf and sscanf!
                   1130: 
                   1131: 0.5.10:
                   1132:   I actually saw that I can not only merge the errno handling code of
                   1133:     the system calls on x86, I can also merge the rest (including the
                   1134:     arguments) except for setting the system call number.  All those
                   1135:     system calls are now just a jump to a unified system call handler.
                   1136:     I got rid of x86openclose again.  The savings are substantial:
                   1137:     chown from embutils went from 7664 to 7184 bytes!
                   1138:     If I'd move the system call wrappers to assembly language, I could
                   1139:     even reduce the alignment (does not matter since it's just a jump
                   1140:     anyway) and get rid of the "ret" behind each jump (one byte per
                   1141:     system call!)
                   1142: 
                   1143: 0.5.9:
                   1144:   added memchr, strpbrk, strstr, strtol, isspace (hehe)
                   1145:   fixed strdup
                   1146:   fixed return values for strcpy and strcat (thanks to Norbert Berzen)
                   1147:   Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
                   1148:     (no signed integers, only strings and unsigned integers (but
                   1149:     supporting octal, hex and decimal).  Thanks, Olaf!  (by the way:
                   1150:     that code must be wonderful, I don't understand it at all *bg*)
                   1151:     Olaf's printf does understand padding like in "%08d" and "%8d" and
                   1152:     automatically pads pointers with '0'.
                   1153:   Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
                   1154:   Thanks to proton for inspiration on this.
                   1155:   The new x86 start code also does not reference exit any more, thus saving
                   1156:   64 bytes for executables that don't call exit explicitly.
                   1157:     [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
                   1158:   Moved errno and environ to start.S, saving no byte binary size but
                   1159:     speeding up compilation and slightly shortening dietlibc.a ;-)
                   1160:   For x86: joined open and close into one assembler file, sharing the
                   1161:     errno handling.  This is a feasibility test and it actually saves a
                   1162:     few bytes.  I think I will reimplement the _syscall[1-6] macros on
                   1163:     all platforms now to share the errno handling code for them.
                   1164: 
                   1165: 0.5.8:
                   1166:   fixed strchr to be able to look for 0.
                   1167: 
                   1168:   added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
                   1169:   memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
                   1170:   strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
                   1171:   contributed by Olaf Dreesen)
                   1172: 
                   1173:   added execvp, getcwd
                   1174: 
                   1175:   fixed __xmknod
                   1176: 
                   1177:   Note: can it be that the ftw interface really is so broken that I
                   1178:   cannot implement it without having to implement some searching data
                   1179:   structure?  I included an experimental ftw implementation that will
                   1180:   not follow symlinks.
                   1181: 
                   1182: 0.5.7:
                   1183:   oops, if_nametoindex was broken!
                   1184: 
                   1185: 0.5.6:
                   1186:   ported to ppc-linux.
                   1187:   fixed i386 sigsetjmp (I mistyped the function name)
                   1188:   included sigjmp.c
                   1189: 
                   1190: 0.5.5:
                   1191:   added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
                   1192:   actually, it wasn't fork that wasn't working for sparc, it was pipe.
                   1193:   I fixed it now.
                   1194:   dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
                   1195:   fixed readdir to use getdents and not the intel inline asm
                   1196: 
                   1197: 0.5.4:
                   1198:   ported to sparclinux (sparc32 only).  Beware: does not work yet.
                   1199:   added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
                   1200: 
                   1201: 0.5.3:
                   1202:   added tcsetattr and getenv to compile e3
                   1203: 
                   1204: 0.5.2:
                   1205:   added vhangup, tcgetattr, isatty and memcmp for fgetty
                   1206:     (http://www.fefe.de/fgetty/)
                   1207:   added localtime from uC-libc.
                   1208: 
                   1209: 0.5.1:
                   1210:   stat and friends actually work now.  Yuck!  Another case of
                   1211:     translation between kernel and userland.  Why can't the kernel
                   1212:     people and the libc people simply agree on a standard?
                   1213:   removed many unnecessary includes to speed up compilation.
                   1214:   added -fomit-frame-pointer and i386 compilation target to reduce code size.
                   1215:   inlined socketcall to reduce code size.
                   1216:   "load" and "compile" are examples for djb code.
                   1217: 
                   1218: 0.5:
                   1219:   Olaf Dreesen contributed a much smaller implementation of malloc and friends.
                   1220:   each object file is now treated with "strip -x -R .note -R .comment"
                   1221:   split each system call into a separate object file
                   1222:   added ntohs, htons, alarm, if_indextoname and if_nametoindex
                   1223: 
                   1224: 0.4.1:
                   1225:   oops, the strchr implementation was wrong.  Thanks Jens Laas!
                   1226: 
                   1227: 0.4:
                   1228:   copied opendir and friends from uC-libc.
                   1229:   added getservent and getservby* in gerservent.c
                   1230: 
                   1231: 0.3:
                   1232:   remove readdir system call
                   1233:   added getdents system call
                   1234:   added getpwnam/getpwuid implementation in getpwnam.c
                   1235:   added a few string functions (in str*.c)
