Update.cvs/libc-ud-960807cvs/libc-960808

Thu Aug  8 01:41:43 1996  Ulrich Drepper  <drepper@cygnus.com>

	* elf/Makefile: Undo change of Tue Aug  6 14:27:11 1996.
	* elf/dl-support: Add definition of `_dl_sysdep_read_whole_file'.

Thu Aug  8 01:15:59 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/fpu_control.h (_FPU_DEFAULT, _FPU_IEEE): Set
	to 0x137f to allow long double operations.

Sun Aug  4 13:12:05 1996  Richard Henderson  <rth@tamu.edu>

	Bug Fixes:

	* nss/nsswitch.c (_res): Remove redundant variable definition.
	The real one is in resolve/res_init.c, and having both prevents
	using -fno-common when building the shared library.
	* sunrpc/rpc_prot.c (_null_auth): Same.  Original is in rpc_common.c.

	* sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as
	a .bss object not a COMMON symbol.

	* sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load
	$gp before referencing __sigsetjmp symbol.  Retain LITUSE for same.

	Optimizations:

	* sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the
	main loop for better dual-issue on EV5.  Rearrange binary search to
	pipeline better and trim one instruction.

	Cosmetic Changes:

	* time/localtime.c (localtime_r): Move lock declaration back next to
	the comment where it was before the 960724 change.

	* INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.
	The second word is supposed to be the hardware manufacturer.

	* sysdeps/alpha/_mcount.S: Retain LITUSE for __mcount.
	* sysdeps/alpha/setjmp.S: Retain LITUSE for __sigsetjmp_aux.

	* sysdeps/alpha/divrem.h: More local labels, retain LITUSE for _mcount.

	* sysdeps/alpha/alphaev5/add_n.S, sysdeps/alpha/alphaev5/lshift.S,
	sysdeps/alpha/alphaev5/rshift.S, sysdeps/alpha/alphaev5/sub_n.S:
	Same cleanups as with EV4 GMP stuff.

Tue Jul 25 03:30:56 1996  Richard Henderson  <rth@tamu.edu>

	* sysdeps/unix/sysv/linux/Makefile [misc] (sysdep_routines): Add clone.
	* sysdeps/unix/sysv/linux/alpha/clone.S: New file.
	* sysdeps/unix/sysv/linux/i386/clone.S: New file.

Sun Aug  4 00:12:41 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* sysdeps/unix/sysv/linux/gnu/types.h: Declare __fd_mask as
	`unsigned long'.

	* misc/sys/select.h: Declare fd_mask as alias of __fd_mask.

Sat Aug  3 16:20:02 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* sysdeps/unix/sysv/linux/alpha/ioperm.c (platform): Add entry for
 	Mikasa.

	* socket/sys/socket.h (send, __send, sendto): Declare buffer
 	pointer as __const.

	* string/tester.c (main): Test stpncpy.

	* sysdeps/generic/stpncpy.c (__stpncpy): Fix so it works without
 	segfault when called with an N that is not a multiple of four and
 	src[N-1]=='\0'.

	* misc/syslog.c (LogType): New variable.
	(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE,
 	try again with SOCK_STREAM (the Linux syslogd uses a socket of the
 	latter type).
	(vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL
 	terminator as a record-delimiter.  If __send(LogFile) fails,
	call closelog() so logfile gets re-opened next time.

Wed Aug  7 15:15:14 1996  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-open (_dl_open): Add cast to avoid warning.

	* manual/memory.texi: Improve some examples to give readers better
	advice: Use `stpcpy' instead of `strcat' if possible.
	* manual/string.texi: Document `strtok_r' and `strtok'.

	* sunrpc/Makefile: Move `+gccwarn' definition before inclusion
	of Makeconfig.
	[$(cross-compiling)=no]: Change test before making librpcsvc
	to this from $(cross-compile).
	Reported by Andreas Schwab.

Tue Aug  6 14:27:11 1996  Ulrich Drepper  <drepper@cygnus.com>

	* elf/Makefile (routines): Move dl-sysdep to here...
	(rtld-routines): ...from here.  This should make static linking
	work again.

	* locale/setlocale.c: Add local variable `lock' and add code to
	`setlocale' to avoid simultaneous changing of global data.

	* catgets/catgets.c (catopen): Use `__strdup' instead of `strdup'.
	* catgets/open_catalog (__open_catalog): Use `__stpcpy', `__open',
	`__fstat', `__read', `__mmap', `__munmap' and `__close' instead
	of unprotected names.
