	* jcf.h (COMPARE_FILENAMES): New macro similar to "strcmp" to
	compare file name components depending on the case-sensitivity
	or otherwise of the host file system.

	* jcf-path.c (add_entry): Use COMPARE_FILENAMES instead of
	"strcmp" to compare file name components.
	Use IS_DIR_SEPARATOR instead of comparing directly against
	DIR_SEPARATOR.
	(jcf_path_extdirs_arg): Use IS_DIR_SEPARATOR instead of
	comparing directly against DIR_SEPARATOR.
