This is a great suggestion, thanks!
Is there any chance that something like smack64 would be integrated
into the main trunk of clang?

Since the main reason why I started this discussion was to hopefully
come up with a solution that would ultimately not require a patch to
clang to be applied whenever somebody would like to use it with SMACK.

Thanks!
