I agree, but that is not how it is done right now - and that it didn't
work for me was just a side effect of me not having COMPAT_AOUT_M68K
defined.
What my change does is just remove the (bogus) dependency on that option.
All GENERIC kernels already duplicate rval[0] to a0.
So how about this: I commit the patch (with syscall_fancy added) for now
and then start collecting a table of missing stubs in the m68k libc.
Once we have added all missing stubs, we'll make the a0 copy #ifdef COMPAT_50?
