need to remain a constant. I tried using an inline function without
success. If all fails I will need to define them all individually using an
ifdef for different endian systems. But this would be my last resort.

Best use inline functions for both ID1 and MAKE_ID. The compiler should
optimize away the calls and do a constant concatenation.
