On windows what I want is actually more complex. Assuming a
make_absolute(relative, base) I expect:

make_absolute("/foo", "/bar") -> "/foo"
make_absolute("foo", "/bar") -> "/bar/foo"
make_absolute("c:foo", "a:/bar") -> throw an error?
make_absolute("c:/foo", "a:/bar") -> "c:/foo"
make_absolute("/foo", "a:/bar") -> "a:/foo"

I understand that this is not at all portable, but it would be good
to have system specific hooks to handle this sort of thing.
