Yes. I'm replying there, please follow up on boost.build.

It was this way before. However Ilya Sokolov told me that
PROCESSOR_ARCHITECTURE is wrong -- it tells you what processor you have,
not what kind of OS you have. And you cannot run 64-bit binaries on
a 32-bit windows.
According to Ilya, PROCESSOR_IDENTIFIER is x86 on win32, whatever the
actual processor might be.
On win64, PROCESSOR_IDENTIFIER is supposed to be always AMD64.

Hmm, this contradicts the statement above.

Yeah, this seems about right.
I've checked in the attached patch to SVN HEAD, would you please check if it works
