----------------------------------------------------------
The Fl::add_fd() API is partially inconsistent because some of the methods
explicitly use 'int', but the callback typedefs use FL_SOCKET. With the
definition of FL_SOCKET below we can have different data sizes and
different signedness of socket numbers on *some* platforms.
