	assume that they reside in the tools/gen_scripts directory and find
	the root of glibmm based on that instead of assuming that the name of
	the root directory is glibmm.

	* gio/src/gio_enums.defs.patch: Add this patch file to streamline the
	enum generation so that keeping the custom Gio::HOST_WAS_NOT_FOUND
	enum value is easier.
