This seems to affect one of the packages I sponsor as well:
If gcc-4.0 is going to puke on lots of packages that use -O3, doesn't it
make more sense to upload a patched gcc-4.0 for m68k that silently
changes the optimization level back to 2 untile the problem with the
compiler can be fixed rather than upload and recompile a large number of
packages for every architecture?
