1997-01-28 04:23 Ulrich Drepper <drepper@cygnus.com> * version.h (VERSION): Bump to 2.0.1. * posix/getopt.c: Handle another problem introduced by the nonoption_flags array. We must be able to work with reordered argv arrays. Reported by Andreas Schwab. 1997-01-28 02:38 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/i386/clone.S: Correct handling of new 1997-01-27 17:34 Thorsten Kukuk <kukuk@weber.uni-paderborn.de> * nis/rpcsvc/yp_prot.h: Correct definitions and types in file so that it works with yp.h. 1997-01-27 13:28 Ulrich Drepper <drepper@cygnus.com> * malloc/malloc.h (__malloc_initialized) [_LIBC]: Define as __libc_malloc_initialized so that this variable is not shared with other users of GNU malloc. Suggested by Martin von Loewis <martin@mira.isdn.cs.tu-berlin.de>. * mcheck.h: Correct typo. Use malloc/ instead of new-malloc/. * sysdeps/i386/Makefile (CFLAGS-dl-load.c, CFLAGS-dl-reloc.c): New variables to prevent warnings. * sysdeps/i386/dl-machine.h (fixup): Add prototype and declare using attribute regparm. (ELF_MACHINE_RUNTIME_TRAMPOLINE): Rewrite so that no register is changed by the resolver code. 1997-01-14 14:20 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * malloc/malloc.c (weak_variable): Define. (__malloc_initialize_hook, __free_hook, __malloc_hook, __realloc_hook, __memalign_hook): Make them weak definitions. 1997-01-26 11:35 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/getdents.c: Don't write beyond buffer limits, correctly take structure padding into account, use correct offset when resetting the stream, change heuristic to assume an average name length of 14 characters. 1997-01-25 18:06 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/alpha/termbits.h: Protect against multiple inclusion. See ChangeLog.6 for earlier changes.
