The above is not needed:
- If MACH_ATARI_ONLY, MACH_IS_ATARI is hardcoded to 1, so the
compiler will optimize-away the else part. In that case,
"ALLOWINT | 0x200" == "ALLOWINT".
- If MACH_AMIGA_ONLY, MACH_IS_ATARI is hardcoded to 0, and
the compiler will optimize-away the other part.
return (flags & ~ALLOWINT) != 0;

}
(or whatever compiler flag we have to indicate we're not building a
multi-platform kernel)
