Let's add in CC Gaby, in the testsuite I see the warning triggering outside
templates for a testcase coming from a bug report of him,
g++.old-deja/g++.other/cond5.C, we have:

enum E1 {e1 = -1};
enum E2 {e2 = -1};

  int j;

  j = (i ? e1 : e2);    // { dg-warning "mismatch" }

Shall we not warn by default? Shall we give the warning a name (which?) and add
it to -Wall? To -Wextra? Neither?
