That is going to be tough, as in C in a macro, there is no way to really
determine what type name you were given. The only thing standard C has
to offer to help is "sizeof", but that doesn't help you, obviously.
(sizeof(float) == sizeof(int)).

In C++, you'd have "typeid", but then you'd also have C++, so that's a
hard pass.

However, would you be willing to settle for

X_INT(i, 1)

?

Ciao,
