--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Should it complain only when the expressions are the same (e.g. token-wise), or
even when just two different expressions have the same value?
I mean, say:
enum X { E = 5, F = 5 };
int i = cond ? E : F;
int j = cond ? x + 3 : x + 2 + 1;
int k = cond ? sizeof (x) : sizeof (y);
etc.
