Indeed. I wasn't aware of this. Sorry.

I'm trying to extend tests/test-verify.c to cover this case, but with
#include "verify.h"
enum {
abc = (verify_true (1 + 1 == 2), 7)
};
I'm still getting the gcc error
"enumerator value for 'abc' is not an integer constant"
What's the right syntax for using verify_true inside an enum initializer?
