G++ enums 'underlying type'

Subject: G++ enums 'underlying type'

Hi everyone,

assuming something specific about g++ 'underlying type' (7.2/5) will alow me to remarkably simplifiy the implementation of tr1/type_traits/is_enum: is it signed or not? Basing on some simple experiments on x86, seems always wide either like an int or a long: is this correct in general?

Thanks in advance for any help,
Paolo.
