[M3devel] CM3 on Leopard

[Darko]

No, that's actually my idea of pain - the scripts never seem to work  
for me. But I'll give it a try because I need to have a go at the  
(byte) alignment problem evident with the current Intel Darwin  
compiler at some point. I've actually never really had a problem with  
Mac OS revisions beyond a cfg file tweak or a rollback of gcc versions.
