1997-02-09 02:59  Ulrich Drepper  <drepper@cygnus.com>

	* version.h (VERSION): Bump to 2.0.2.

	* posix/Makefile (routines): Add getopt_init.
	* posix/getopt.c: Don't get environment variable with nonoption
	flags here.  Depend on __getopt_nonoption_flags variable filled
	somewhere else.  This is necessary since the variable must be
	removed even when getopt isn't used in case exec(2) gets called.
	* posix/getopt_init.c: New file.  Initialize __getopt_nonoption_flags
	and remove environment variable.
	* sysdeps/i386/init-first.c: Call __getopt_clean_environment.
	* sysdeps/mach/hurd/i386/init-first.c: Likewise.
	* sysdeps/stub/init-first.c: Likewise.
	* sysdeps/unix/sysv/linux/init-first.c: Likewise.

	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Recognize
	AT_PAGESZ entry in auxiliary vector and store value in _dl_pagesize.

	* sysdeps/generic/crypt-entry.h: Return EOPNOTSUPP when DES
	encryption is wanted.

	* libio/vsnprintf.c: If MAXLEN is 0 return 0.
	* stdio/vsnprintf.c: Likewise.
	Reported by Philip Blundell <pjb27@cam.ac.uk>.

1997-02-07 17:43  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/sysd-stdio.c: Include <errno.h>.
	Change PTR to void *.
	* sysdeps/posix/vdprintf.c: Change PTR to void *.
	Reported by Brian Oxley <boxley%dev.cm.ssb.com@clipper.ssb.com>.

1997-02-06 14:38  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	and gid_t.

	* sunrpc/auth_unix.c (authunix_validate): Fix type of second
	argument.

1997-02-06 14:29  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/Makefile (extra-objs): Don't zap previous value.
	* Makefile (before-compile): Likewise.  Don't add gnu/lib-names.h
	twice.

1997-02-06 14:19  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/m68k/brk.c: Add workaround for
	braindamage (sigh!).

	GNU tr don't grok it.

1997-02-03 21:13  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/socketbits.h [__GNUC__<2] (struct cmsghdr):
