      Do not prefix cache_base with a "/". Doing so will lead to FcStrBuildFilename()
	composing paths that contain double slashes, e.g. in FcDirCacheProcess(). If
	FcDirCacheBasenameMD5() returns a cache_base that is prefixed with a "/", the
	call to FcStrBuildFilename() in FcDirCacheProcess() will compose a path that
	contains double slashes and this double-slashed path will then be passed to
	FcDirCacheOpenFile(). This won't cause any harm on Linux because Linux just
	ignores multiple slashes in paths but on other operating systems multiple
	slashes in paths are not allowed so FcDirCacheOpenFile() will fail on those
	platforms because of the double slash in the path.
