Indeed. I had lot of troubles implementing my Win32POSIX binding.

No. There is also some problems with file locking if my memory is right,
and some package just can't* be implemented on Win32.

Pascal.

* Of course it is always possible (see Cygwin for example) but the work will
  be very big. We need to provides a complete POSIX emulation not just a
  binding.
