Subject: [PATCH] remove the check for dlopen again - didn't work as intended
 for #idfef

2007-01-16  Michael Schumacher  <schumaml@cvs.gnome.org>

	* configure.ac: remove the check for dlopen again - didn't work as
	intended
	* babl/babl-extension.c: for #idfef WIN32, #define dl* functions
	to their Windows equivalents (LoadLibrary, GetProcAddress,
	FreeLibrary).
