 Yes! Thank you very much for the rapid fix!

 This needs further works (probably worth for another PR?). So, please
 feel free to close this PR.

 With code inspection, atari does not have this problem. However, yes,
 m68k ports especially old ones have many similar-but-slightly-different
 codes that should be unified in the future (Your work for 68040 was

 for another PR...
