The issue on win32 with mingw is in some way the cross shared libraries
exception problem, I installed a try {} catch(...){} inside Fl::handle and
it catches my exceptions there.
It seems that in some way we need to have an option to override Fl::handle
to catch exceptions before pass control back to windows operating system
again, Fl::handle is static an probably it should be a method pointer to
allow chaining event listeners.
typedef int (*Fl::handler_func)(int, Fl_Window*);
