Cool - that's the first I've heard of that. I'll take a look.

How I'm planning to structure this is that the configure
tests will have to recognise either x86-64 (for 64-bit)
or x86 (for 32-bit) calls, and anything else (x32) will
get treated as a non-thread-specific credentials system.

That's the safest way to do it until we understand the
implications of that ABI.

H. Peter Anvin is listed as the author and I know Peter
quite well, so I'll get the info from the horses mouth
so to speak :-).

Thanks for pointing that out,

Jeremy.
