[MLton-user] Re: fork() in MLton on Cygwin

[Garbage Collection]

There is a fix for the Cygwin fork/mmap bug in the
current (20040715 and later) developer snapshot
(cygwin.com/snapshots).

Using a recompiled version of MLton and the new Cygwin
dll, all regression tests pass except socket.sml and
textio.2.sml.

I'm including diffs against the current CVS versions
of runtime/gc.c and basis-library/posix/process.sml.

gc.c:
uses mmap/munmap instead of VirtualAlloc/VirtualFree,
but still uses MEMORYSTATUS/VirtualQuery in
showMem/showMaps.

process.sml:
no longer guards the Cygwin.
