[MLton] Does Socket Stuff Work in Cygwin?

[Brent Fulgham]

The echo.sml regression test does not work under
Cygwin because of the lack of 'fork'.  I modified the
echo test to use spawnp, but the program still fails
to work as I would expect (i.e., it never seems to
establish the connection with the other running
process).

Does anyone konw if Cygwin sockets actually work?  Or
am I trying to compare my nonfunctional Mingwin with a
nonfunctional Cygwin implementation?

Thanks,
