156 Fri Sep 10 04:35:16 CEST 1999 Wichert Akkerman <wakkerma@debian.org>
158 * #define USE_GNU before including file.c so we get some extra O_* flags

178 * configure.in: Allow compilation in a different directory

184 * syscall.c: Likewise.
186 Wed Aug 4 18:01:50 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

247 * linux/sparc/syscall.h: Update used sparc-linux syscalls.
248 * linux/sparc/syscallent.h: Match 2.2.9 system calls.
249 * file.c: sparc-linux asm/stat.h uses dev_t etc. types,

274 + some layout and other minor fixes
275 + add some m68k-specific things to linux/syscallent.h. Note that m68k

326 * util.c (umovestr) [LINUX]: Handle Linux like SunOS4
327 instead of SVR4. That is, read a few bytes at a time
328 to avoid overrunning the end of the stack.
330 Fri May 31 01:48:49 1996 J. Richard Sladkey <jrs@world.std.com>
332 * version.c: Version 3.1 is released.
334 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
336 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
337 as well since that's where glibc declares it. Go figure.
338 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
339 instead of sigcontext_struct since glibc v5+ apparently
340 plays games with the native OS namespace.
341 From David Mosberger-Tang <davidm@AZStarNet.com>.
343 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>
345 * version.c: Version 3.0.14 is released.
347 * aclocal.m4 (AC_STRUCT_MSG_CONTROL): New macro.
348 * configure.in: Add call to AC_STRUCT_MSG_CONTROL.

351 Reported by Henrik Storner <storner@osiris.ping.dk>.
353 * configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
354 sys/filio.h and sys/stream.h and remove check for poll.
355 * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
356 Handle old and new styles of argument passing for select on Linux.
357 * ioctl.c, stream.c: Conditionalize stream code on presence of
358 sys/stream.h instead of poll because glibc implements poll but
359 not the rest of the stream interface.
360 * signal.c [LINUX]: Standardize on the name sigcontext_struct.
361 (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
363 * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
364 * util.c (umoven, umovestr): Move data in long-sized chunks
365 at a time, instead of hard coding it to be 4.
366 From David Mosberger-Tang <davidm@AZStarNet.com>.
368 Mon May 20 01:19:36 1996 J. Richard Sladkey <jrs@world.std.com>

373 * signal.c [HAVE_ASM_SIGCONTEXT_H]: Conditionally include
374 asm/sigcontext.h to define sigcontext_struct and don't define it
375 locally if the header is present.
377 * syscall.c (nerrnos{0,2}): Correct size computation.
379 * Makefile.in: Remove dependencies and rules relating to files
380 normally found in the os directory. Because of the new scheme we
381 don't know precisely where they come from. Sigh.
382 * signalent.sh: Make it work for sunos4, linux, and svr4.
383 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
384 to traditional make syntax. Add signalent.h to files which can
385 unconditionally be rebuilt. Prevent signalent.h from being
386 unconditionally being rebuilt since it's customized.
387 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
388 Use versions built by {ioctlent,errnoent,signaltent}.sh.
389 * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS
392 Sun May 19 17:14:09 1996 J. Richard Sladkey <jrs@world.std.com>

396 * Makefile.in, linux/Makefile.in: Rewrite clean, distclean,
397 and maintainer-clean rules.
398 * defs.h, ioctlsort.c: Make ioctl code member unsigned.
399 * ioctl.c, ioctlsort.c (compare): Perform explicit checking
400 for less, greater, and equal since subtraction on two's
401 complement numbers isn't an order relation (it isn't transitive)!
402 * linux/Makefile.in: Add rules for the signalent.h file.
403 * linux/alpha/Makefile.in: New file.
405 Sun May 19 01:12:28 1996 J. Richard Sladkey <jrs@world.std.com>

417 based on personality.
418 * {sunos4,svr4,linux{,/alpha}}/signalent.h: New files.
419 Suggested by Tom Dyas <tdyas@eden.rutgers.edu>.
421 * util.c (upeek): Handle case where ptrace returns a long
422 and sizeof(long) != sizeof(int).
423 From Richard Henderson <richard@twiddle.tamu.edu>
425 Fri May 17 21:03:36 1996 J. Richard Sladkey <jrs@world.std.com>

431 * ipc.c (sys_msgrcv) [LINUX]: Conditionalize definition of ipc_wrapper.
433 * linux/dummy.h: Handle missing library support for {send,recv}msg.
434 Reported by Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
436 * linux/syscall.h (sys_utimes): Fix a typo in the declaration.
437 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
439 Fri May 17 00:50:06 1996 J. Richard Sladkey <jrs@world.std.com>
441 * version.c: Version 3.0.10 is released.
443 * Makfile.in: Add os/arch to includes so that a given arch
444 (like alpha) can override the native arch (like i386).
445 * configure.in: Check for sendmsg.
447 * net.c: Make sendmsg and recvmsg dependent on an autoconf
448 test. Reported by Michael E Chastain <mec@duracef.shout.net>.
450 * acconfig.h, configure.in: Detect the alpha.
451 * ioctl.c: Handle the alpha.
452 * defs.h: Make some members long for the alpha. Define
453 some register nicknames. Add support for WAITEXECVE.
454 * file.c [ALPHA]: Support the alpha for statfs. Add
455 osf_statfs and osf_fstatfs for the alpha. Make damn sure
456 major and minor results are suitable for passing to printf.
457 * signal.c, syscall.c: Support the alpha.
458 * process.c: Add alpha user offsets.
459 * most files: Use %l? for printf arguments since
460 most are now longs for the alpha.
461 * linux/alpha/{errnoent.h,ioctlent.{h,sh},syscallent.h}:
463 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.

495 * Makefile.in (distclean): Fix it for subdirectories.
497 * sunos4/syscallent.h, svr4/syscallent.h: Fill in the new
498 sys_flags member for each defined system call.
