2007-03-07  Tor Lillqvist  <tml@novell.com>

	* configure.in
	* modules/basic/Makefile.am
	* modules/basic/basic-win32.c: Make building with Uniscribe (using
	the <usp10.h> header) mandatory. Mingw's w32api headers do include
	usp10.h now so one doesn't need to copy it from the Platform SDK
	any longer. At runtime using Uniscribe is still optional,
	depending on whether usp10.dll is found or not. I think it
	isn't necessarily present on Windows 2000 machines, for instance.

	* modules/basic/basic-win32.c (lang_name): Instead of a hardcoded
	case statement, use GetLocaleInfo() to get the language ISO639
	code.
	(charset_name): Remove, unused.
	(itemize_shape_and_place, uniscribe_shape, basic_engine_shape):
	Constify the PangoAnalysis parameter to match the prototype of
	PangoEngineShapeClass::script_shape().
