* sysdeps/vax, sysdeps/unix/bsd/vax: Directories and all files removed.
These are now in the ports repository.
* time/mktime.c (leapyear, ydms_tm_diff): Year is of type
long int, not int, to avoid problems when tm_year == INT_MAX
and tm_mon > 12.
(__mktime_intenral): Compute year using long int arithmetic,
not int arithmetic, to avoid problems on hosts where time_t
and long are 64 bits but int is 32.
* time/mktime.c [!_LIBC] (__mktime_internal): Define to
mktime_internal, to avoid clashes with any __mktime_internal
function defined in the standard library.
* time/mktime.c (__isleap): Remove; all uses replaced by:
(leapyear): New function, which avoids overflow by not adding
1900 to year before testing whether it is a leap year.
* debug/execinfo.h: Remove __THROW from backtrace prototype.
2004-10-22 Jakub Jelinek <jakub@redhat.com>
* sysdeps/i386/Makefile (CFLAGS-backtrace.c): Add -fexceptions.
* sysdeps/i386/backtrace.c: Include <bits/libc-lock.h>, <dlfcn.h>,
<stdlib.h> and <unwind.h>. Remove <bp-checks.h> include.

fn pointers resp. macros.

$(config-sysdirs) for shlib-versions files.
* Makeconfig ($(common-objpfx)soversions.i): Replace shell loop with
use of ...

match any DEFAULT line before emitting anything, so DEFAULT can come
later in the concatenation of shlib-versions files.

* sysdeps/unix/sysv/linux/Versions (libc: GLIBC_2.3.4): New errlist.
* sysdeps/gnu/errlist.c: Regenerated

(generated): Add errlist-compat.h.
* sysdeps/gnu/errlist.awk: Make output #include <errlist-compat.h> to

* debug/Makefile ($(objpfx)catchsegv): To support multilib
platforms, use $LIB in path to slibdir.
2004-10-19 Jakub Jelinek <jakub@redhat.com>

Use mktemp to create segv_output file.
