man page says: CONFORMING TO SVr4, 4.3BSD, POSIX.1-2001.
OS/2 doesn't have it and probably does not have anything comparable,
nor will probably BeOS and similar.
Which is why I said we need a configure check.
However attached is a version that might work on Windows already.

Doesn't really fit into mpcommon yet, however there are some things I should
move there.
