Ahh, I see.  There are two bugs in guile-gtk that prevent it from
working.  The first is that no automatic type conversion used for
composite objects (including the one that takes substrings to normal
strings), and the second is that guile-gtk accepts substrings as valid
types but can't deal with them then.

I have fixed the second bug, so now your example will produce a "Wrong
type argument" error.  The first bug needs more work and more thought,
because of memory management issues and of mode `out' parameters.  You
can work around the first bug by explicitely using string-copy to get
from a substring to an equal normal string.

My current thinking is to convert a composite of mode `in' by copying
it, and one of mode `out' or `inout' by modifying it in place.  Any
thoughts about this?

You can now use gtkconf-guile-gtk-version to get at the guile-gtk
version.  gtkconf-version will now reflect the version of Gtk+ that is
actually active.

	* build-guile-gtk (emit-funcs): The `string' type now only accepts
	non-substrings.
	
	* gdk-1.2.defs, gdk-1.3.defs (gdk_pixmap_create_from_xpm): New.

	* gtk/config.scm.in (gtkconf-libdir): Construct from
	$myexecprefix.
	(gtkconf-default-version): New variable, takes old role of
	gtkconf-version.
	(gtkconf-version): Initialize to `#f', will bet set to the right
	value once the glue code has been loaded.
	(gtkconf-guile-gtk-version): New variable, reflects version of
	guile-gtk package itself.
	* gtk/dynlink.scm (gtk-version-set): Take version number as string
	and construct prefix from it.  Set gtkconf-version.
	Changed all callers.
