From e447481751bcdc3c913a03e3dc80ad6a659269dd Mon Sep 17 00:00:00 2001

Subject: [PATCH] The GNU coding standards specify that CFLAGS should be left
 for 	users to set. 	* Makefile.in (CFLAGS): Let configure determine the
 default value 	for this.  Don't 	have it default to DEFS. 
 (${SUBDIR}): Pass CFLAGS down to submakes, not DEFS. 	(lib-src/Makefile,
 src/Makefile): Edit the default value for 	CFLAGS into these files, not
 DEFS. 	* configure.in (CFLAGS): Choose a default value for this - "-g" 
 normally, or "-g -O" if we're using GCC.  Edit it into the 	top-level
 Makefile.

	* configure.in: When scanning the machine and system description
	#include files, write their names to conftest.c properly.

	* configure.in: In configuration name case for Apallos running
	Domainios, set opsys, not opsysfile.

	* configure.in: Use the autoconf AC_CONFIG_HEADER macro to produce
	src/config.h, instead of AC_OUTPUT; the latter overwrites
	src/config.h even when it hasn't changed, puts a makefile-style
	comment at the top even though it's C code, and produces a
	config.status script which doesn't do the job right.

	* configure.in: Add AC_LN_S test, so we can tell whether or not we
	can use a symbolic link to get the X Menu library into src.
	* Makefile.in (LN_S): New variable.
	(src/Makefile): Edit the value of LN_S into this makefile.
