c++: pedwarn for empty unnamed enum in decl [PR67048]
[dcl.dcl]/5 says that
enum { };
is ill-formed, and since r197742 we issue a pedwarn. However, the
pedwarn also fires for
enum { } x;
which is well-formed. So only warn when {} is followed by a ;. This
should be correct since you can't have "enum {}, <whatever>" -- that
produces "expected unqualified-id before ',' token".
