--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed.  Even GCC 4.6 ICEs, g++34 says:
ee.C:1: error: invalid use of undefined type `enum E'
ee.C:1: error: forward declaration of `enum E'
ee.C:1: error: a comma operator cannot appear in a constant-expression
ee.C:1: error: enumerator value for `b' not integer constant
