Ummm, even using #warning will prevent it from any non-GCC compiler from
compiling the file. If you use #error, it prevents any pre-ISO C compiler from
compiling the file (even if OCTETS_PER_BYTE_POWER is defined), unless there is
a space before the '#' (since old traditional cpp's didn't support leading
spaces).
