But DJGPP at least takes the trouble of providing that POSIX
compatible library.  And there is a Free (as in Freedom) MS-DOS
available (don't know if DJGPP runs on it though).

That said, I'd probably object if someone would contribute a DJGPP
port with all its #ifdef's today.  But we've had DJGPP support in the
tree for ages, and as long as there's someone actively working on
DJGPP support I feel that I can't ask for its removal.
