DJGPP is known to support Windows 3.1 and 95 fully, and I believe I've heard
success reports about 98. Windows NT also works; the only gotcha is that you
can't use long file names, but only their short aliases. AFAIK, the only
problems with Windows in general are: no null pointer protection, and
`usleep' may not always work.
