  Yep, and yep later this week.  Want to run full gcc-4.3.3-1 testsuite first,
but fortran results looked promising:

  That's with the Cygwin DLL simply patched to schedule an atexit call to
dll_global_dtors directly after the exe's global dtors get run.

  (Also, going to fix libffi once and for all (both for 4.3.3 and HEAD), this
will I hope clean up a ton of java FAILs as a knock-on effect.  Am working on
that first while waiting the three days or so it takes to run the full tests...)

    cheers,
