grep shows that /sys/src/cmd/cc/lex.c is relevant,
since it contains

	s = lookup();
	if(s->macro) {
		...
	}
	yylval.sym = s;
	if(s->class == CTYPEDEF || s->class == CTYPESTR)
		return LTYPE;
	return s->lexical;

for the relevant bit of lexing.  you could trace back and 
see how s->class gets set.
