From e48f96382f237c0edad5c446eca867092406a51d Mon Sep 17 00:00:00 2001
From: Roland McGrath <roland@gnu.org>
Date: Mon, 10 Mar 2003 09:11:13 +0000
Subject: * sysdeps/unix/make-syscalls.sh: Generate $(compile-syscall) for

	assembler command.
	* sysdeps/unix/Makefile (compile-syscall): New variable.
	Pass -g0 to compiler for assembling syscall stubs from stdin.

	* sysdeps/i386/sysdep.h [HAVE_CPP_ASM_DEBUGINFO]
	(STABS_CURRENT_FILE, STABS_CURRENT_FILE1, STABS_FUN, STABS_FUN_END):
	Define these to do nothing.

	* configure.in: New check for -g on .S files.
	* configure: Regenerated.
	* config.make.in (have-cpp-asm-debuginfo): New variable.
	* config.h.in (HAVE_CPP_ASM_DEBUGINFO): New #undef.
	* Makeconfig (ASFLAGS): New variable, if undefined and
	$(have-cpp-asm-debuginfo), take options matching -g% from $(CFLAGS).
	* Makerules (compile.S, COMPILE.S): Use $(ASFLAGS).
