ghc 4.02 on NT, posix library

[Mircea Draghicescu]

1)  Using stdInput or stdOutput produces the error message

D:/ghc/ghc-4.02/lib/libHSposix.a(PosixFiles.o)(.text+0x20c4):ghc1000.c: undefined 
reference to `mkfifo'
collect2: ld returned 1 exit status

Replacing them with intToFd 0, intToFd 1 works fine.

2) The following program crashes:

import Posix
main = do
  maybePid   <- forkProcess
  case maybePid of
    Nothing   -> return ()
    Just pid  -> return ()

3) handleToFd is not documented in the posix library page.

Thanks.
