OK, I am sending this stupid patch. Better than nothing.

Of course. And this is not good. For example:
void func(void)
{
struct B *b; struct C *c; struct D *d;
_Generic(a,
int: b,
void*: c,
default: d
) ->mem++;
}
output:
1:6 def f func void ( ... )
3:18 func def . v b struct B *
3:31 func def . v c struct C *
3:44 func def . v d struct D *
4:18 func --- v a bad type
5:33 func --m . v b struct B *
6:33 func --m . v c struct C *
7:33 func --m . v d struct D *
8:11 func -m- m D.mem bad type
But I do not know how to improve it without serious complications, and
(so far) I think it doesn't worth the effort.
