It has nothing to do with the compiler - it's a function of the underlying
MSVCRT library. And you are correct. See initdb.c for an example - after
canonicalising it can and does happily use / as the separator. The only
trouble you have is in dealing with Windows command interpreters, when you
have to make sure that you quote the path (you have to do that anyway, as
the path might also include spaces).
