Hi Richard,
The 0b is a GCC extension. When you compile with the options "-pedantic -std=c99 -Wall", the you see the warnings like "binary constants are a GCC extension". At the end of the day, I would like to remove these GCC extensions. But at first I would like that splint falls through this code, instead of the parsing error. The (default) option "+gnuextensions" does not do the trick. I did not consider using a preprocessor for converting the 0b. Do you have a pointer to such a preprocessor?
