To get a more robust Gtk+ build I use to include the minimum
required moules with-in the respective library. This is simple 
with Pango (just link in pango/modules/modules/basic-$(PLATFORM).c);
the optional rest is build as modules. This way the user gets - even
with a broken setup - the ability to read error meesages.

For gtk the pixbuf loaders XPM and PNG are similar important,
(IIRC crashing sooner or later without them) so I'd like 
to include them as well. 
Though possible with the current code it also requires to include 
_all_ wanted loaders, cause one has to undefine USE_GMODULE. 
[Would be ok for loaders included in Gtk+, but dissallows to use
 external loaders like the librsvg one.]

The following patch does make USE_GMODULE independent of 
INCLUDE_$(format). It reflects the current needs outlined
above, i.e. not all io-$(format).c are changed yet, but you get 
the idea ;-)

Does this patch have any chance to be accepted ?

Thanks,
