As an added bonus, I see that my patch set also included an old m68k patch that
had been sitting in my tree, which fixes a crash when -m68040 is defined. I may
have submitted it to port-m68k before. It hasn’t been tested with the new
compiler either. Here’s that patch separately. It only matter when TARGET_68881
&& TUNE_68040.
