Octave very slow on Cygwin

Yes, it is a problem with GCC, also related to using setjmp/longjmp to
implement exception handling.  See

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14563

for some additional history.

It's nice that reverting to setjmp/longjmp for exception handling is
supposed to have fixed an obscure problem involving functions throwing
exceptions that were used as callbacks by win32api functions.  But it
seems to have caused a lot of trouble for other projects (namely, us).
So how about it if some Octave-on-Windows users put some pressure on
the Cygwin/GCC people to undo this "bug fix".
