I just checked in a fix/workaround for this problem.

IMO, gcc really should be using __cxa_atexit.  The change I just checked
in is a workaround for the fact that there is no way for the atexit
handler to know that a to-be-called function was registered in a dso.

If gcc was using __cxa_atexit this probably would not have been a
problem, although there would still be more cygwin DLL work required
to make this work at dll unload time.
