Is the compiler binary itself a 68020 or a 68000 binary? The point being,
although the 68000 support should be "good enough", it's still possible
that there's a miscompile in there, because it's less tested than the
68020 counterpart. If the compiler binary is 68020, that's "good news" in
the semse that it's probably only an Atari-specific bug, which means it's
99.999% something in the RTL.

On a related note, maybe we should think about setting up a 68000
testsuite run somehow, because so far we only test on 68020 (and under
Linux and QEMU), I think.
