There's no reason you can't make the built-in automatically folded by
the front-end so that you still get a constant expression.

I understand that this isn't the syntax you write, in that you have to
write:

  static ptr32_t x = __builtin_ptr32 (f);

instead of:

  static void (*far x)() = f;

but I think you're much more likely to actually get the built-in
approach to work correctly in C++.
