--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Testcase without the >s
#define E(c, e) if (c) e

int
foo (int n)
{
  switch (n)
    {
    case 0:
      E (1, return 0);
    case 1:
      return 1;
    }
  return 2;
}

In C we actually warn about this since the warning has been introduced.
