 * pick1.h - Compiler-dependent defines for PIC compilers
 * This file allows porting of PIC-INTERCAL output files to different
 * compilers. Most compilers will require this file to be modified;
 * as written at the moment, it's ANSI C that invokes undefined
 * behaviour (in a way that might plausibly produce correct
 * results).
