     * configure.in (HAVE_XFT, HAVE_FREETYPE, HAVE_LIBOTF)
     (HAVE_M17N_FLT): Don't check for these unless HAVE_X11.

This change

2008-10-30  Emanuele Giaquinta  <emanuele.giaquinta <at> gmail.com>

	* configure.in: Check fontconfig always.

causes unnecessary linking with libfontconfig when configured
--without-x or --with-ns:

$ ldd -u -r src/emacs
Unused direct dependencies:
	
	/usr/lib/libfontconfig.so.1

For Emacs.app, it can't be even removed with -Wl,--as-needed since
user-defined LDFLAGS do not propagate to the link rule (yet).  A
straightforward solution seems to be the following:

2009-02-10  Yavor Doganov  <yavor <at> gnu.org>  (tiny change)

	* configure.in: Check for fontconfig only if HAVE_X11=yes.
