Uhm, your answer is ambiguous. So, is it possible, to haven
signed char / unsigned char / char as three separate Numerics
registered ?

I am not sure, if there is a real gain of using intX_t types. In the
end it is a test on if the type is a Numeric with or without signess
and a certain bit width, as do_compare ignores the type name
completely.

Hm, in the clang importer I just register the builtins as
their corresponding numerics, as I get information about
signess, and bitwidth. I saw, that GCCXML did not give any information
about the sign though.
I like this solution, as I need no apriori information for building
a registry.
