+I sent several private replies to Tomi this morning while being\r
+sleepy. But they were not so great replies anyway.\r

+What about implimenting a compat version of canonicalize_file_name ?\r
+that function is a gnu extension, but since we only call realpath with a\r
+NULL second argument, it might be slighltly simpler to test/google for.\r
