How do you think we can use scoped enum with underlying types in a portable
way? I guess the use that states that an enum is a char expect the sizeof
this enum to be the same as the sizeof char, isn't it?

I have been working a little bit on a enums library that provides such a
feature (see
https://svn.boost.org/svn/boost/sandbox/enums/libs/enums/doc/html/index.html).
Let me know if you are interested.
