4 * This file allows porting of PIC-INTERCAL output files to different
|
|
|
5 * compilers. Most compilers will require this file to be modified;
|
|
|
6 * as written at the moment, it's ANSI C that invokes undefined
|
|
|
7 * behaviour (in a way that might plausibly produce correct
|
|
|
8 * results).
