--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Ha, they almost look like they might be valid and do something useful.
Compiles without error on 4.3, before any C++0x scoped enum support, so it's
not a consequence of that.
The C front-end does diagnose it:
enum.cc:1:6: error: two or more data types in declaration specifiers
long enum E { one, two, three };
^~~~
enum.cc:1:25: warning: useless type name in empty declaration
long enum E { one, two, three };
^~~~~
