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

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