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.
