return NULL for malloc(0) or realloc(p, 0). (This should be done differently than wasting one byte, but alas...) * Moved "add'l libraries" option in Makefile to an earlier place. * Remove argument compatibility hacks (b) and (c). * Add grey2mono, dither2mono and mono2grey to imageop. * Dup the fd in socket.fromfd(). * Added new modules mpz, md5 (by JH, requiring GNU MP 1.2). Affects Makefile and config.c. * socketmodule.c: added socket.fromfd(fd, family, type, [proto]), converted socket() to use of getargs().
