Yes i think so. Those lowercase versions have always been there for all m68k 
platforms, with and without underscores (if you don't use -ansi), while the 
uppercase versions have only been patched in by the mint patch, for 
compatibility with some very old ports. Also, there is no uppercase equivalent 
for -m68030 or better, they all define only __M68020__. So, although that is 
fixed now, the code should check for __mc68020__ instead.
