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

Tue Oct 15 15:13:16 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makerules (sysd-Makefile): Fix command so that it works in the
	subdirectories.
	(BUILD_CFLAGS): Change back using $(..) instead of
	$(common-objpfx), the latter fails in the toplevel directory when
	$(objdir) is relative.

	* sysdeps/posix/Makefile (mk-stdiolim): Likewise.

Tue Oct 15 23:39:48 1996  Ulrich Drepper  <drepper@cygnus.com>

	* time/sys/time.h [__USE_BSD]: Add prototype for ualarm.
	Reported by Andreas Jaeger.

	The available nlist implementation is not generally usable.
  	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.

	* po/Makefile (distribute): Add header.pot.

	* sysdeps/unix/sysv/linux/m68k/sysdep.h (POUND): Macro removed,
	replaced by `&'.
	(PSEUDO_END): Provide definition to use .size directive.
	(PSEUDO): Don't interpret negative return values less than -128 as
	syscall error.
	* sysdeps/unix/sysv/linux/m68k/syscall.S (syscall): Likewise.

	* sysdeps/m68k/bsd-_setjmp.S: Use PSEUDO_END macro to provide
	.size directive.
	* sysdeps/m68k/bsd-setjmp.S: Likewise.
	* sysdeps/unix/sysv/linux/m68k/clone.S: Likewise.

	* sysdeps/unix/sysv/linux/m68k/syscall.S: Likewise.
	* sysdeps/unix/sysv/linux/m68k/sysdep.S: Use PSEUDO_END instead of
	explicit .size directive.

	* libio/iogets.c: Warn when gets is used.
