On both amd64 and i686! Untested on the other arches, but should Just
Work on the LP64 ones (may need ABI-specific support for returning u64s
like i686 does).

See commit messages for details. Based on 0.7.3-6.4.

Anyway, please consider copying these patches in. I can't be the only

 for that matter.)
