[MLton-user] mingw or cygwin

[Stephen Weeks]

The Cygwin mlton binary is run from the Cygwin shell and produces
executables that require the cygwin dll.  The MinGW mlton binary is
run from the Windows Command Shell (or whatever it's called) and
produces executables that run standalone, without the cygwin dll.  The
MinGW basis is somewhat impoverished, mostly (perhaps exclusively) in
terms of the Posix structure.  A number of functions in the Posix
structure will raise SysErr.
