So, before your fix, same_type_p was returning true?
enum { e1 = -1 };
enum { e2 = -1 };
int j;
void foo(void) {
j = 0 ? e1 : e2;
}
g++ 4.3.2
tt.cc:6: warning: enumeral mismatch in conditional expression: ‘<anonymous
enum>’ vs ‘<anonymous enum>’
So, the warning is intended, and the fact that we did not warn before was a
bug. However, it is not clear to me how this code can be dangerous. But the
warning is very very old.
