Not exactly. Cygwin links in some other components, e.g. newlib. It
has a different C runtime and headers, i.e. not based on msvcrt.dll. The
two are sufficiently different that I'd recommend a true cross compiler
rather than trying to mess with -mno-cygwin.
Of course, it'd be nice to have Cygwin building gcj natively too... what's
the obstacle? Just boehm-gc? It ought to work, at least with
win32-threads.c.
