Update.

	* string/bits/string2.h: Fix aliasing problems.
	* sysdeps/i386/i486/bits/string.h: Likewise.
	* sysdeps/i386/bits/string.h: Likewise.

1998-12-28  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/dl-machine.c: Handle shared library profiling.
	* elf/rtld.c (dl_main): Don't call malloc() between
	re-relocating the dynamic linker and running the application's crt0.

1999-07-21  Paul D. Smith  <psmith@gnu.org>

	* sysdeps/generic/glob.c: Move getlogin{,_r} prototypes below
	glob.h to get __P() macro.

	* posix/fnmatch.c (internal_fnmatch): Use K&R definition syntax,
	not ANSI.
	(__strchrnul): This won't exist outside GLIBC, so create one.

1999-07-25  Jakub Jelinek   <jj@ultra.linux.cz>

	* sysdeps/unix/sysv/linux/sparc/bits/types.h: Always define __qaddr_t.
	__ino64_t should be 32bit unsigned type on sparc32.
	Define __off64_t to __quad_t instead of __int64_t.
	Make __pic_pid_t unsigned on sparc32.

1999-07-25  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* localedata/tst-rpmatch.sh: Use "&" instead of "§" to avoid a bug
	in bash 2.03.
