+	* src/base/ftobjs.c: Improvement of resource fork handler for POSIX,
+	http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
+	(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
+	format or .dfont, to simulate the face index number counted by ftmac.c.
+	(IsMacResource): Return the number of scalable faces correctly.
+
 2006-12-10  Werner Lemberg  <wl@gnu.org>
 
 	* builds/toplevel.mk (version): Protect against `distclean' target.
