2005-09-15  Keith Packard  <keithp@@keithp.com>

	* configure.in:
	Cairo now no longer implicitly adds fontconfig and freetype
	to include paths, so cairo-5c must explictly depend on them

	Use XInitThreads, as it's necessary for stable operation.
	Requires at least one bug fix not yet in Xlib CVS to work
