Ulrich Drepper df777c40c1 Update.
1998-08-20 16:01  Ulrich Drepper  <drepper@cygnus.com>

	* elf/ldd.sh.in: Redirect warnings and error messages to stderr.
	* elf/ldd.bash.in: Likewise.

	* elf/sln.c: Avoid warning for no main prototype.

	* sysdeps/unix/sysv/linux/alpha/bits/fcntl.h: Remove O_READ and
	O_WRITE.
	* sysdeps/unix/sysv/linux/mips/bits/fcntl.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/fcntl.h: Likewise.

	* sysdeps/unix/sysv/linux/alpha/bits/fcntl.h: Add F_SETSIG and
	F_GETSIG.
	* sysdeps/unix/sysv/linux/bits/fcntl.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/fcntl.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/fcntl.h: Likewise.

1998-08-20  Philip Blundell  <pb@nexus.co.uk>

	* sysdeps/arm/fpu/ieee754.h: Move to...
	* sysdeps/arm/ieee754.h: ... here.

	* sysdeps/arm/__longjmp.S: Put return value in correct register.
	Don't set the condition flags unnecessarily.
	* sysdeps/arm/fpu/__longjmp.S: Likewise.  Restore floating point
	registers correctly.

	* sysdeps/arm/dl-machine.h: Fix problems with profiling code
	(patch from Scott Bambrough).

	* sysdeps/arm/sysdep.h (CALL_MCOUNT): Add missing semicolons.

	* csu/initfini.c (_init): Don't check whether __gmon_start__ is
	NULL, just call it unconditionally.
	(__gmon_start__): Provide stub version as a weak symbol.

1998-07-30  Philip Blundell  <philb@gnu.org>

	* sysdeps/unix/sysv/linux/arm/init-first.h: New file (from patch
	by Scott Bambrough)

	* sysdeps/unix/sysv/linux/arm/errlist.c: New file; ARM tools don't
	like `@' in .type directives.

	* sysdeps/arm/bsd-setjmp.S: Use PLT for procedure call.
	* sysdeps/arm/bsd-_setjmp.S: Likewise.

	* sysdeps/arm/dl-machine.h: Set __libc_stack_end.

1998-08-20  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/unix/sysv/linux/mips/bits/fcntl.h (F_SETOWN): Correct value.
	(F_GETOWN): Likewise.

	* sysdeps/unix/sysv/linux/bits/siginfo.h (SI_SIGIO): Add it (from
	Linux 2.1.117).

1998-08-20  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/glob.c [_LIBC]: Define __stat only if not
	already defined.

1998-08-14  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>

	* nis/nss_compat/compat-grp.c: Set errno to ENOENT if we have no
	more entries.
	* nis/nss_compat/compat-initgroups.c: Likewise.
	* nis/nss_compat/compat-pwd.c: Likewise.
	* nis/nss_compat/compat-spwd.c: Likewise.
	* nis/nss_nis/nis-alias.c: Likewise.
	* nis/nss_nis/nis-ethers.c: Likewise.
	* nis/nss_nis/nis-grp.c: Likewise.
	* nis/nss_nis/nis-hosts.c: Likewise.
	* nis/nss_nis/nis-initgroups.c: Likewise.
	* nis/nss_nis/nis-network.c: Likewise.
	* nis/nss_nis/nis-proto.c: Likewise.
	* nis/nss_nis/nis-pwd.c: Likewise.
	* nis/nss_nis/nis-rpc.c: Likewise.
	* nis/nss_nis/nis-service.c: Likewise.
	* nis/nss_nis/nis-spwd.c: Likewise.

	* nis/rpcsvc/yp.h: Generate new without 1024 byte limits.

	* nis/ypclnt.c: Try binding dir only first time, could be to old.

	* nis/yp_xdr.c: Remove 1024 byte limit.
	* nis/ypupdate_xdr.c: Likewise.

	* nis/nss_nis/nis-publickey.c: Make sure, nobody could send
	wrong data.
