Annotation of dietlibc/CHANGES, revision 1.122
1.115 fefe 1: 0.11:
2: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 3: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 4: add floor, ceil and memchr prototypes.
5: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 6: cleaner errno vs __errno_location handling
7: add placeholder iconv (iconv_open will always return EINVAL)
8: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
9: initialization of getaddrinfo.
1.119 fefe 10: fix vsnprintf %X (printed lower case)
1.120 fefe 11: I wrote a new getopt. It appears to actually work (it is POSIX
12: compliant, it does not sort argv like the GNU version) and is only
13: a little over 300 bytes on x86.
1.121 fefe 14: Guillaume Cottenceau just wrote me that strncat should be even more
15: broken than it already is: it should append n bytes AND THEN \0!
16: I wonder how many programmers have produces off-by-one errors here...
1.122 ! fefe 17: Fix regexec offset return. autoconf now believes that diet libc has
! 18: POSIX regular expressions.
1.115 fefe 19:
1.74 fefe 20: 0.10:
21: update getpagesize.
22: add personality.
1.75 fefe 23: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 24: add putchar (apparently arm-linux-gcc will substitute printf("\n")
25: with putchar('\n') behind your back...?!
1.77 fefe 26: import include/scsi/ from glibc.
1.78 fefe 27: add iopl.
1.80 fefe 28: add execl and sigdelset prototypes.
29: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 30: add RPC headers (no code yet).
1.82 fefe 31: add mlockall, munlockall
1.83 fefe 32: make "diet gcc foo.c" work.
33: added Sun RPC code and removed as many warnings as possible in a
34: heroic act of self-mutilation.
35: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 36: added getpass. mount from util-linux actually compiles now!
37: fix the sig*set routines. mount actually works now *bg*
38: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 39: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 40: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 41: add res_init.
42: add asprintf (ugh, what an ugly function).
1.89 fefe 43: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 44: add ut_name alias to ut_host in struct utmp.
45: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 46: add sysinfo, recvmsg, sendmsg.
1.93 fefe 47: add endmntent, getmntent, setmntent.
1.94 fefe 48: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 49: add setenv.
50: remove __restrict from mntent.h, add __restrict__ removal alias for
51: older gcc versions in sys/cdefs.h.
52: add rlim_t, sig_atomic_t declarations.
53: add sigsetjmp #define for __sigsetjmp (oops).
54: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 55: add a gruesome hack to printf floating point to accept %f and kludge
56: together support for %.2f. Don't look at the code, please!
1.98 fefe 57: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 58: imported fix for entlib by Jeff Garzik.
1.100 fefe 59: add glob implementation from Guillaume Cottenceau (Thanks!!)
60: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 61: add REG_ICASE and word start/end handling to my regular expressions.
62: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 63: wrap getcwd to comply to man page (the syscall returns the number of
64: bytes, not the buffer)
65: add realpath.
1.103 fefe 66: fix vfprintf.
1.104 fefe 67: fix *scanf %s zero termination.
68: add abs, labs, llabs.
1.105 fefe 69: add <sys/io.h>, ioperm syscall.
70: add flock to <sys/file.h>
1.106 fefe 71: fixes to bsearch and the regular expressions.
1.107 fefe 72: add fake herror.
1.108 fefe 73: add scandir and alphasort.
1.109 fefe 74: add killpg
1.110 fefe 75: implemented a gross hack to make libpthread compile when
76: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 77: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 78: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 79: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
80: for sending a patch.
1.114 fefe 81: add getserv*.
82: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
83: "search" from resolv.conf.
1.74 fefe 84:
1.73 fefe 85: 0.9:
1.65 fefe 86: fixed initgroups (oops)
1.66 fefe 87: Cleanup appending file open for stdio (thanks, James Antill)
88: imported vfprintf fix from James Antill.
1.67 fefe 89: add fnmatch
90: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 91: Olaf added character classes to *scanf.
1.69 fefe 92: Put object and library files into a separate directory (bin-$ARCH).
93: Add "cross" make target to make all architectures.
94: Add "diet" program and man page.
1.70 fefe 95: Add getgrnam, getgrgid
1.71 fefe 96: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 97: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 98:
1.64 fefe 99: 0.8:
1.34 fefe 100: vsnprintf(0,...) estimated the length of strings with a padding width
101: incorrectly.
1.35 fefe 102: new reboot() from Olaf.
1.36 fefe 103: added prototypes for getsockopt and setsockopt.
1.39 fefe 104: added experimental sem* and shm*
1.38 fefe 105: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 106: added setvbuf (only changes mode, not buffer)
1.41 fefe 107: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
108: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 109: added qsort() and bsearch(). Benchmark on 1000 random ints:
110: glibc: 679414 cycles qsort and 3352 cycles bsearch
111: diet libc: 300010 cycles qsort, 553 cycles bsearch
112: I have no idea why glibc is so slow.
1.43 fefe 113: added __isnan (references by libm.a from glibc).
114: added popen() and pclose(). Now the diet libc can link slsh (from
115: S-Lang!)
1.44 fefe 116: corrected usleep. It was more of an msleep until now.
1.45 fefe 117: corrected __dtostr (it looped when trying to format "0.0").
118: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 119: added ungetc (does it work?)
1.47 fefe 120: added inet_aton (yuck!)
1.50 fefe 121: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 122: added h_errno and __h_errno_location
123: added inet_ntoa
1.49 fefe 124: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 125: add bcopy, index, rindex macros
126: add isgraph and isxdigit
1.52 fefe 127: add strftime (ugh!!!)
1.53 olaf 128: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 129: Jeff Garzik contributed a spec file. I put it in contrib and hope
130: everbody knows what to do with it...
131: Olaf checked in a ton of libpthread stuff.
1.55 fefe 132: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 133: add large file backwards compatibility support (so gzip will run on
134: kernel 2.2 and 2.0)
1.57 fefe 135: added shutdown
1.58 fefe 136: added nice
137: added pseudo-locale support for is* (they are now weak aliases,
138: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
139: overwrite the default is* functions.
1.59 fefe 140: added liblatin1.a
1.60 fefe 141: added tzfile implementation (does it work for anyone else?)
1.61 fefe 142: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 143: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
144: Thanks!
1.63 fefe 145: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 146:
1.21 fefe 147: 0.7.2:
148: added several prototypes to already implemented functions and
149: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 150: added prototypes for process group and dup syscalls. Thanks to
151: Abraham again. He also contributed an implementation for daemon(),
152: an ugly BSD hack. I decided to diversify the lib/ directory a
153: little and now created a libugly/ directory for stuff like system()
154: and daemon() ;-)
155: added libstdio and moved all that stdio crap from lib/ there. The
156: idea is to start separating now what we will separate for shared
157: libraries anyway.
1.26 fefe 158: optimized x86 unified-syscall by Olaf.
1.27 fefe 159: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
160: limits.h instead)
161: added remove.c and enough cruft to limits.h to make it compile lzo,
162: lzop and bzip2.
1.28 fefe 163: added mktime, asctime_r, asctime and ctime (needed for gzip).
164: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 165: format some day (man tzfile, ugh!) :-(
1.29 fefe 166: added unlink prototype to unistd.h.
167: added gmtime and gmtime_r.
1.31 fefe 168: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 169: removed readdir glibc compatibility cruft.
1.31 fefe 170: removed stat glibc compatibility cruft.
1.32 fefe 171: oops, my fread was broken for pipes.
1.33 fefe 172: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 173:
1.9 fefe 174: 0.7.1:
1.11 fefe 175: optimized away the static arrays from __ltostr and __lltostr.
176: optimized away the static arrays (and more!) from strtoul and strtoull.
177: added system (by Olaf).
1.12 fefe 178: added tolower and toupper
1.13 fefe 179: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 180: added clone for mips (by Olaf).
181: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 182: added pause for all (by Olaf).
1.17 fefe 183: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 184: added isupper and islower.
185: added putc and putchar as macros.
1.17 fefe 186: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
187: insightful discussions and patches I partially used for the last three)
1.18 fefe 188: added getpriority and setpriority (also by Abraham)
1.19 fefe 189: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 190: oi, setjmp and longjmp were broken on other platforms, too!
191: Thanks to Sébastien Côté for reporting this.
1.9 fefe 192:
193: 0.7:
1.6 olaf 194: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 195: Initial dynamic loading glue for i386, also by Olaf.
196: We don't have a dynamic loader yet, so this is not yet usable.
197: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
198: vsprintf, writev, all by Olaf.
1.2 fefe 199: imported readdir fix from Guillaume. Mhh, can the kernel interface
200: really be this broken?
1.3 fefe 201: Found a kludgy way to detect whether the kernel includes define struct
202: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
203: not work for you, please tell me!
1.4 fefe 204: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 205: Fixed stdio line buffering. The code was already there but I forgot
206: to mark stdio and stdout as line buffered. This should really be
207: done dynamically using isatty, though.
1.8 fefe 208: Removed superfluous "if (1)" in execvp.c
1.1 cvs 209:
210: 0.6.14:
211: *scanf did not append the 0 byte for %s.
212: added creat and changed creat to call open directly instead of open64.
213: did for fread what 0.6.10 did for fwrite.
214: repaired buffered stdio a little (line buffering is still not
215: supported).
216: [All of these bugs have been reported by Guillaume. Thanks!]
217: added __pure__ to strchr and strrchr in <string.h>
218:
219: 0.6.13:
220: included COPYING to make clear that the diet libc is covered by the
221: GNU General Public License (and _not_ the LGPL). That means that
222: you need to obtain a license from me if you want to use the diet
223: libc in a proprietary program that you want to distribute.
224: The x86 unified syscall swapped arguments #4 and #5 and noone
225: noticed until now! Thanks to Guillaume Cottenceau for reporting
226: this!
227: The malloc had a subtle bug with small allocations that could cause
228: segfault. Guillaume reported it, Olaf fixed it.
229:
230: 0.6.12:
231: added assert, statfs and fstatfs
232: added include/net/if.h so fget compiles again.
233:
234: 0.6.11:
235: added putenv.
236:
237: 0.6.10:
238: fixed fwrite. It returned the number of bytes written, not the number
239: of records. Thanks to Albert D. Cahalan for pointing this out.
240: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
241: added brk and sbrk. harold@nb.com.sg made me do it.
242:
243: 0.6.9:
244: fixed execvp not to return on ENOENT
245: did for {open|read|close|seek|tell}dir what I did for stat before.
246: The glibc compatibility part is currently non-functional.
247: fixed white space handling in sscanf " (" would not match " (".
248: fixed printf to accept 'l' flag.
249: fixed getpwuid (ignored last line)
250:
251: 0.6.8:
252: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
253: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
254: added strlcpy and strlcat from OpenBSD.
255: added stat64, fstat64 and lstat64.
256: added endian.h and made ending of strlen.c endianness-aware
257: added string routines size tweak to dietfeatures.h. Most of the
258: string routines have been unrolled. This is up to three times as
259: fast but creates up to three times larger code. Now you can disable
260: the unrolling.
261: added sendfile.
262: I also added pread. It works on x86 and sparc but not on ppc and mips.
263: I have no idea what's going on. strace disagrees with the kernel.
264: Can anyone help? I asked the Linux kernel mailing list for help, too.
265: added a few aliases of the type __libc_open for open. nm on
266: libpthreads.so indicates that we will need them.
267:
268: 0.6.7:
269: the sources now compile without warnings with -Wall.
270: printf now prints "(null)" when %s is passed NULL. This can be
271: removed with WANT_NULL_PRINTF in dietfeatures.h
272: added vfprintf, execl, ttyname.
273: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
274: __dietfstat so they can use the normal kernel struct stat.
275: stat, lstat and fstat are now C wrappers that convert to the glibc
276: struct stat. So we can avoid that overhead for programs that use
277: dietlibc headers.
278:
279: 0.6.6:
280: changed the Makefiles so you can now set CFLAGS on the command line
281: added memccmp (analogous to memccpy) and strncmp.
282: Olaf fixed another bug in the sparc unified syscall.
283: Paul Clifford contributed a C version of his strlen.S that is much
284: more efficient than the previous strlen on all platforms! It also
285: looks like technology from Roswell. ;-}
286: added a "real" stdio. Well, almost. Please contribute!
287: added dietfeatures.h so you can remove features you don't need.
288: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
289: stdio now works with simple programs and minigzip from libz.
290: stdio uses some major trickery to avoid linking the stdio, stderr and
291: stdout (and reserving space for them) when they are not used.
292:
293: 0.6.5:
294: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
295: most of them bugs in the new header files, but also missing sigset
296: functions.
297: Paul Clifford contributed an assembly strlen.S for ARM and fixed
298: several bugs.
299: Fixed ppc/setjmp and mips/pipe.
300: Olaf contributed a new sparc unified syscall.
301:
302: 0.6.4:
303: declared is* static inline in getservent.
304: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
305: changed strlen to return 0 when passed NULL.
306: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
307: Scientist who actually implemented this without access to a MIPS
308: box, just from reading the architecture manual. And it worked out
309: of the box.
310: started a set of system includes, mainly so that I can use lcc and
311: my alpha-linux cross compiler (which is unable to cross-compile
312: glibc). diet libc can now be compiled without any include files
313: from a normal libc. The includes do declare more than diet libc
314: currently delivers and they are still far from complete for real
315: applications.
316: I will only add assembly versions that are smaller _and_ faster than
317: the C version. Larger routines are only accepted if they are called
318: very often and are substantially faster.
319: added i386 assembly strchr, which is smaller and faster than the old
320: version. It is, however, larger than the version contributed by
321: proton (thanks, anyway).
322: added i386 strlen (31% faster, 14% smaller)
323: "make t" will now create a map file called "mapfile".
324:
325: 0.6.3:
326: added sys_errlist, strerror and perror
327: added isblank
328: added atol
329:
330: 0.6.2:
331: mmap for ARM didn't compile. Thanks, Paul!
332:
333: 0.6.1:
334: split mmap into the architecture specific subdirectories.
335: getenv now copes with environ==NULL, thanks Paul Clifford.
336: Paul also contributed a smaller ARM startup code.
337:
338: 0.6:
339: strcat returned the wrong result. Thanks, Dietz Pröpper.
340: strtod now understands a negative exponent (oops, thanks Bertram Barth)
341: Port to arm-linux-gnu, but on the Netwinder I use for testing the
342: __dtostr does not work (I have no idea why!)
343: The MIPS port now uses (much smaller) non-PIC code. That means that
344: the applications you link against diet libc also have to be compiled
345: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
346: Thanks to Ralf Bächle for helping me with this!
347: I made subdirectories for the architectures and use VPATH to override
348: VPATH so that make finds the source file automatically. That should
349: simplify the sources greatly.
350: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
351: ARM and MIPS now also have setjmp and longjmp
352: "compile" and "load" are now make targets. Use them for djb programs.
353: added contrib/elftrunc.c which will remove unnecessary ELF headers.
354: Again, contributed from Olaf. Great work!
355:
356: 0.5.12:
357: printf also does signed numbers.
358: If you don't use atexit, dietlibc now does not link exit, only _exit.
359: *printf now correctly returns the number of bytes written.
360: Olaf contributed experimental sscanf and vsscanf implementations.
361: If passed NULL as buffer, snprintf will not write anything but still
362: return the number of bytes it would have written.
363: Initial MIPS port! (Oh, the agony!)
364: No setjmp and longjmp support yet! Please contribute!
365: I even implemented unified syscalls for MIPS. Still, MIPS code is
366: almost twice the size of SPARC code. If anyone knows why: please
367: tell me!
368:
369: 0.5.11:
370: I implemented new unified syscalls for x86, sparc and ppc, this time based
371: on .s files and not .c files, and I moved the syscalls into
372: subdirectores to clean the dietlibc sources up a little.
373: A binary consisting of printf("%s is %d\n","olaf",23) is now
374: 2864 bytes on sparc
375: 2488 bytes on intel
376: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
377: to make a few more applications work.
378: Olaf Dreesen also implemented some unified syscall stuff for x86.
379: He discovered that with our unified syscall interface it actually
380: costs <10 bytes total to make all system calls thread safe!
381: I implemented atexit() (can register up to 4 callbacks).
382: I implemented strtod and __dtostr (the opposite). Now we can add
383: floating point support to vsnprintf and sscanf!
384:
385: 0.5.10:
386: I actually saw that I can not only merge the errno handling code of
387: the system calls on x86, I can also merge the rest (including the
388: arguments) except for setting the system call number. All those
389: system calls are now just a jump to a unified system call handler.
390: I got rid of x86openclose again. The savings are substantial:
391: chown from embutils went from 7664 to 7184 bytes!
392: If I'd move the system call wrappers to assembly language, I could
393: even reduce the alignment (does not matter since it's just a jump
394: anyway) and get rid of the "ret" behind each jump (one byte per
395: system call!)
396:
397: 0.5.9:
398: added memchr, strpbrk, strstr, strtol, isspace (hehe)
399: fixed strdup
400: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
401: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
402: (no signed integers, only strings and unsigned integers (but
403: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
404: that code must be wonderful, I don't understand it at all *bg*)
405: Olaf's printf does understand padding like in "%08d" and "%8d" and
406: automatically pads pointers with '0'.
407: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
408: Thanks to proton for inspiration on this.
409: The new x86 start code also does not reference exit any more, thus saving
410: 64 bytes for executables that don't call exit explicitly.
411: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
412: Moved errno and environ to start.S, saving no byte binary size but
413: speeding up compilation and slightly shortening dietlibc.a ;-)
414: For x86: joined open and close into one assembler file, sharing the
415: errno handling. This is a feasibility test and it actually saves a
416: few bytes. I think I will reimplement the _syscall[1-6] macros on
417: all platforms now to share the errno handling code for them.
418:
419: 0.5.8:
420: fixed strchr to be able to look for 0.
421:
422: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
423: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
424: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
425: contributed by Olaf Dreesen)
426:
427: added execvp, getcwd
428:
429: fixed __xmknod
430:
431: Note: can it be that the ftw interface really is so broken that I
432: cannot implement it without having to implement some searching data
433: structure? I included an experimental ftw implementation that will
434: not follow symlinks.
435:
436: 0.5.7:
437: oops, if_nametoindex was broken!
438:
439: 0.5.6:
440: ported to ppc-linux.
441: fixed i386 sigsetjmp (I mistyped the function name)
442: included sigjmp.c
443:
444: 0.5.5:
445: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
446: actually, it wasn't fork that wasn't working for sparc, it was pipe.
447: I fixed it now.
448: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
449: fixed readdir to use getdents and not the intel inline asm
450:
451: 0.5.4:
452: ported to sparclinux (sparc32 only). Beware: does not work yet.
453: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
454:
455: 0.5.3:
456: added tcsetattr and getenv to compile e3
457:
458: 0.5.2:
459: added vhangup, tcgetattr, isatty and memcmp for fgetty
460: (http://www.fefe.de/fgetty/)
461: added localtime from uC-libc.
462:
463: 0.5.1:
464: stat and friends actually work now. Yuck! Another case of
465: translation between kernel and userland. Why can't the kernel
466: people and the libc people simply agree on a standard?
467: removed many unnecessary includes to speed up compilation.
468: added -fomit-frame-pointer and i386 compilation target to reduce code size.
469: inlined socketcall to reduce code size.
470: "load" and "compile" are examples for djb code.
471:
472: 0.5:
473: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
474: each object file is now treated with "strip -x -R .note -R .comment"
475: split each system call into a separate object file
476: added ntohs, htons, alarm, if_indextoname and if_nametoindex
477:
478: 0.4.1:
479: oops, the strchr implementation was wrong. Thanks Jens Laas!
480:
481: 0.4:
482: copied opendir and friends from uC-libc.
483: added getservent and getservby* in gerservent.c
484:
485: 0.3:
486: remove readdir system call
487: added getdents system call
488: added getpwnam/getpwuid implementation in getpwnam.c
489: added a few string functions (in str*.c)
