/*
* FILE: stdefs.h
* BY: Christopher Lee Fraley (cf0v@spice.cs.cmu.edu)
* DESC: Defines standard stuff for inclusion in C programs.
*
* 1.0 ( 6-JUN-88) - created. (cf0v)
* 1.1 (30-JUN-88) - moved GetUHWORD def here. (cf0v)
* 1.2 (11-JUL-88) - added ffail() defs. (cf0v)
* 1.3 (25-JUL-88) - added dB() and undB() defs. (cf0v)
* 1.4 ( 8-AUG-88) - added stuff used by apple & new NULL def. (cf0v)
