On the 'define_stack' there are also the macro parameters, such
as 'ap' and 'type' in "#define va_arg(ap, type) ..."

See parse_define at tccpp.c:1199:
    s = sym_push2(&define_stack, varg | SYM_FIELD, is_vaargs, 0);

Hence to get these names properly you have to use
    get_tok_str(sym->v & ~SYM_FIELD, NULL)

Otherwise it would print as bogus anonymous label (at tccpp.c:338):
        } else if (v >= SYM_FIRST_ANOM) {
            /* special name for anonymous symbol */
            sprintf(p, "L.%u", v - SYM_FIRST_ANOM);
