Not requiring cygwin for the build architecture is a worthwhile goal,
but isn't this what Simon is working on currently?

Maybe a better solution first would be to work on cutting down the size
of ml.  WHen this is done, then I think the double maintainence problem
would be substantially reduced.

I would be hesitant to commit this now, because even this solution
requires cygwin to be installed so that calls to invoke_shell_command
succeed inside the compiler.

Does this limit us to only passing 9 arguments to the compiler?
