Thanks Kevin, got the attachment.

Okay.  I think for now we'll stick with assuming 64bit is stored in the
string.  128bits may be here in a while, but until then I'll tacklet the
simpler problem of 64 vs 32!

For testing, can you access ESS via github (e.g. directly or via MELPA?)

Do you have multiple versions of R on your system for testing?
