Subject: * Makefile.in (DEFS): Deleted; since we're using AC_CONFIG_HEADER,
X-Git-Tag: archive/raspbian/1%29.2+1-2+rpi1^2~5^2~96350
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:///%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:/?a=commitdiff_plain;h=b6472fc16bba795fc499314f8264c3518945bfa0;p=emacs.git

* Makefile.in (DEFS): Deleted; since we're using AC_CONFIG_HEADER,
	this is always just -DHAVE_CONFIG_H.

	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: 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.
