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.
