* flmodule.c: added some missing functions; changed readonly flags of some data members based upon FORMS documentation. * listobject.c: fixed int/long arg lint bug (bites PC compilers). * several: removed redundant print methods (repr is good enough). * posixmodule.c: added (still experimental) process group functions.
