It will be valid. 7.2 [dcl.enum] says:

  6 For an enumeration where e_min is the smallest enumerator and e_max
    is the largest, the values of the enumeration are the values of the
    underlying type in the range b_min to b_max, where b_min and b_max
    are, respectively, the smallest and largest values of the smallest
    bit-field that can store e_min and e_max. It is possible to define
    an enumeration that has values not defined by any of its enumerators.

AFAIK the intent of that paragraph is to make OR-ing enumerators
yield a defined enumeration value.
