Hmmm. Lemme see... OK, gcc is clearly at fault here (IMHO). So it's the responsibility of the gcc build script to fix those. Eg.: - CT_ARCH_ARCH can take any value acceptable by -march - the build script mangles that value to build a value suitable for --with-arch That's the idea... But I'm no m68k expert, here...
