Owen Taylor 69915aa710 Implement a search path for GTK+ modules. 
Sat Sep  8 16:19:02 2001  Owen Taylor  <otaylor@redhat.com>

 	* gtk/gtkmain.c: Implement a search path for GTK+ modules.

 	* configure.in gtk/gtkrc.c gtk/Makefile.am: Look for modules
 	in gtk-2.0/<type>/major.minor.(micro-binary_age) rather
 	than in gtk-2.0/major.minor.micro/<type>/. This
 	works better for a search path for modules.

 	* gtk+-2.0.pc.in gtk+-2.0-uninstalled.pc.in: Add
 	gtk_binary_version variable holding major.minor.(micro-binary_age).

 	* modules/input/Makefile.am (moduledir): Fix installation
 	directory to match change in lookup location.

 	* gtk/gtkmain.c (gtk_init_check): Remove OS/2 code for dll
 	suffixes. Needs to be handled in g_module_build_path().

	* gtk/gtkrc.c gtk/queryimmodules.c: Use g_build_filename() where
	appropriate.
