bug#7936: 23.2; libfontconfig not used when linking temacs

[Peter Dyballa <Peter_Dyballa@Freenet.DE>]

Hello!

When compiling GNU Emacs 23.2 the first time in summer with Fink on  
Mac OS X 10.5.8 libfontconfig was linked. Trying to build GNU Emacs  
again, due to supposed problems with libXaw3d, now with MacPorts  
instead of Fink (configure script edited to reflect this),  
libfontconfig is not linked although found by configure:

	checking for fontconfig >= 2.2.0... yes
	checking FONTCONFIG_CFLAGS... -I/opt/local/include
	checking FONTCONFIG_LIBS... -L/opt/local/lib -lfontconfig

Config.log has:

	configure:13478: checking for pkg-config
	configure:13509: result: /opt/local/bin/pkg-config
	configure:13523: checking for fontconfig >= 2.2.0
	configure:13527: result: yes
	configure:13531: checking FONTCONFIG_CFLAGS
	configure:13534: result: -I/opt/local/include
	configure:13537: checking FONTCONFIG_LIBS
	configure:13540: result: -L/opt/local/lib -lfontconfig

A related C header file gets used later:

When configuring with GTK-2 linking succeeds, possibly because of:

	checking GTK_LIBS... -L/opt/local/lib -lgtk-x11-2.0 -lgdk-x11-2.0 - 
latk-1.0 -lpangocairo-1.0 -lXext -lXrender -lXinerama -lXi -lXrandr - 
lXcursor -lXcomposite -lXdamage -lgdk_pixbuf-2.0 -lpangoft2-1.0 - 
lgio-2.0 -lXfixes -lcairo -lX11 -lpng14 -lpango-1.0 -lm -lfreetype - 
lfontconfig -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 - 
lintl -liconv


GNU Emacs 23.2.92 seems to behave similarly.

Email is a wonderful thing for people whose role in life is to be on  
top of things. But not for me; my role is to be on the bottom of  
things. What I do takes long hours of studying and uninterruptible  
concentration.
