You can use forward slashes in paths under Win32, except at the
command prompt.

Even if you switch to use all forward slashes, however, what do
you plan to do about drive letters?  There is no obvious mapping
to anything under POSIX, I think.  Are you planning on disallowing
paths that go anywhere but the current drive under NT?
