90 NOTE: *FIXME* AlbrechtS 13 Apr 2016 (concerning FL_SOCKET)
91 ----------------------------------------------------------
92 The Fl::add_fd() API is partially inconsistent because some of the methods
93 explicitly use 'int', but the callback typedefs use FL_SOCKET. With the
94 definition of FL_SOCKET below we can have different data sizes and
95 different signedness of socket numbers on *some* platforms.
