glibc/sunrpc/rpc_cout.c
Ulrich Drepper 0d204b0a52 update from main archive 961016
Thu Oct 17 01:55:34 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sunrpc/Makefile ($(objpfx)rpcsvc/%.h, $(objpfx)x%.c): Write
	output to $@T and move to $@ later since the new rpcgen will not
	overwrite existing files.

	* po/Makefile (libc.pot): Fix typo.

Sun Oct 13 20:52:07 1996  Thorsten Kukuk  <kukuk@weber.uni-paderborn.de>

 	whether read failed.

Wed Oct 16 14:54:59 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/i386/clone.S: Use JUMPTARGET and
 	PSEUDO_END macro.

Tue Oct 15 21:27:42 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/m68k/sigcontext.h: Removed.

Tue Oct 15 15:52:29 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

  	Especially on the currently supported ELF systems the nlist
 	function comes with the libelf.
	* misc/Makefile (headers): Remove nlist.h.
	(routines): Remove nlist.

	* Makefile ($(objpfx)version-info.h): Include information about
	system the libc is built on in version-info.h file.
