1999-07-25 Ulrich Drepper <drepper@cygnus.com>

+ * 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.
+
+1999-07-25 Ulrich Drepper <drepper@cygnus.com>
+
* iconvdata/euc-kr.c (euckr_from_ucs4): Set cp[0] to '\0' in case
of an error. Patch by Changwoo Ryu <cwryu@debian.org>.
