Cause B programs to fail on startup if they detect alignment issues. 2019-06-17 20:27:13 +00:00			`#define MASK ((1<<SHIFT)-1)`

First draft of the B module code; a module name can now be specified as a compiler flag, which is used to set the name of the patch table. The compiler now understands C preprocessor line directives. Extend the standard library somewhat. 2016-12-29 17:10:21 +00:00			`extern FILE* input_unit;`
