/* FL module -- interface to Mark Overmars' FORMS Library. */
/* This code works with FORMS version 2.2 (if you defined
OBSOLETE_FORMS_CALLS), and 2.3.
FORMS can be ftp'ed from ftp.cs.ruu.nl (131.211.80.17), directory
/pub/SGI/FORMS. */
/* A half-hearted attempt has been made to allow programs using this
* module to exploit parallelism (through the threads module). No provisions
* have been made for multiple threads to use this module at the same time,
* though. So, a program with a forms thread and a non-forms thread will work
* fine but a program with two threads using forms will probably crash (unless
* the program takes precaution to ensure that only one thread can be in
* this module at any time). This will have to be fixed some time.
* (A fix will probably also have to synchronize with the gl module).
