Here is a patch to allow Fl::handle be overridable by a user application,
it comes for me as a need to use exceptions to handle errors in my
application and found a problem with mingw on win32, even using vc++ or
gcc on linux that do works with exceptions very well, the best place I
found to install a global exception catch that is recoverable is at
fl::handle entry point.
