Think about all the scripts > and makefiles containing x86_64... *shiver* Could we live with a slightly modified toolchain that defines both __x86_64__ and __amd64__ ? I'd be more than happy to rename everything so that it was #ifdef __amd64__ and have MACHINE_ARCH=amd64 for $dir/amd64/* etc. But we can't stop defining __x86_64__ since thats what linux and the FSF camp appear to use. Lots of third party stuff will have __x86_64__ ifdefs. > BTW: To what extend is the actual name important? Is it only > 'uname -m' that really matters (toolchain bordercases aside)? Having $MACHINE_ARCH different to #ifdef __$MACHINE_ARCH__ would be an ongoing problem I think.
