"lint" lets very bad code pass

Portability is portability. This is the first time I've heard that lint only
checks for portability to non-UNIX systems. The documentation refers to the
GCOS & IBM dialects of 'C'. Since UNIX runs on IBM mainframes shouldn't it
complain about such things as "if(c<'0')", since this isn't portable to
certain UNIX systems?
