How do I get the fundamental type of an enum?

Question

With a declaration such as:

enum DrawBoldMode : unsigned
{
    DBM_NONE =              0,
    DBM_ITEM =              1<<0,   // bold just the nearest          


        

Answer 1

It should be available as std::underlying_type::type. However, my compiler (GCC 4.6.1) doesn't seem to implement that.

I think it's impossible to implement it with templates, but I could be wrong about that.
