Update.
1998-07-31 17:59 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/generic/bits/byteswap.h: Fix problems with side effects.
* manual/filesys.texi: Document truncate and ftruncate.
Patch by Michael Deutschmann <michael@talamasca.wkpowerlink.com>.
* shadow/putspent.c: Lock stream while generating the output.
* sunrpc/clnt_unix.c: Use ucred instead of cmsgcred again.
(__msgwrite): Rewrite accordingly.
* sunrpc/svc_unix.c: Likewise.
* sysdeps/unix/sysv/linux/Dist: Remove __recvmsg.S and __sendmsg.S.
* sysdeps/unix/sysv/linux/Makefile [$(subdir)==socket]
(sysdep_routines): Remove __sendmsg and __recvmsg.
* sysdeps/unix/sysv/linux/__recvmsg.S: Removed.
* sysdeps/unix/sysv/linux/__sendmsg.S: Removed.
* sysdeps/unix/sysv/linux/recvmsg.c: Removed.
* sysdeps/unix/sysv/linux/sendmsg.c: Removed.
* sysdeps/unix/sysv/linux/recvmsg.S: New file.
* sysdeps/unix/sysv/linux/sendmsg.S: New file.
* sysdeps/unix/sysv/linux/bits/socket.h: Define SCM_CREDENTIALS and
struct ucred. Remove struct cmsgcred.

1998-08-08 14:42 Ulrich Drepper <drepper@cygnus.com>
* argp/argp-help.c: Prepare to be used outside glibc without gcc by
adding usual alloca cruft.
Reported by Eleftherios Gkioulekas <lf@amath.washington.edu>.
1998-04-05 Jim Meyering <meyering@ascend.com>
* lib/regex.c (WIDE_CHAR_SUPPORT): Define.
This now depends on HAVE_BTOWC so systems that lack btowc (like
solaris-2.5.1) don't lose.
1998-08-07 Mark Kettenis <kettenis@phys.uva.nl>
* sysdeps/generic/bits/sigaction.h: Remove definition of SA_DISABLE.
* sysdeps/generic/bits/sigstack.h: Define SS_DISABLE, SS_ONSTACK,
MINSIGSTKZ and SIGSTKSZ. Definitions match BSD.
* hurd/sigunwind.c (_hurdsig_longjmp_from_handler): Use SS_ONSTACK
instead of SA_ONSTACK.
* sysdeps/mach/hurd/sigaltstack.c (__sigaltstack): Renamed from
sigaltstack, and created a weak alias. Use SS_DISABLE and
SS_ONSTACK instead of SA_DISABLE and SA_ONSTACK.
* sysdeps/mach/hurd/sigstack.c (sigstack): Use SS_ONSTACK instead
of SA_ONSTACK. Call __sigaltstack instead of sigaltstack.
* sysdeps/mach/hurd/i386/sigreturn.c (__sigreturn): Use SS_ONSTACK
instead of SA_ONSTACK.
* sysdeps/mach/hurd/alpha/sigreturn.c (__sigreturn): Likewise.

Use SS_DISABLE instead of SA_DISABLE. Use SS_ONSTACK instead of
SA_ONSTACK where appropriate.
* sysdeps/mach/hurd/alpha/trampoline.c (_hurd_setup_sighandler):
Likewise.
* sysdeps/mach/hurd/hppa/trampoline.c (_hurd_setup_sighandler):
Likewise.
* sysdeps/mach/hurd/mips/trampoline.c (_hurd_setup_sighandler):
Likewise.
* manual/signal.texi (Signal Stack): Talk about SS_DISABLE and
SS_ONSTACK instead of SA_DISABLE and SA_ONSTACK in discussion of
the `ss_flags' member of `struct sigaltstack'.
1998-08-05 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>

[USE_IN_LIBIO]: Map __fdopen to _IO_fdopen.
* sysdeps/posix/tempname.c (__gen_tempname): Don't bother checking
__stub_open64, it is never defined.
1998-08-05 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* libio/iofopen64.c: Fix typo. Avoid unnessary casts.
* libio/iopopen.c: Unlink file before freeing it if command
