gcc 3.2.3 config/os/bits/i386/atomicity.h broken

Sorry, if I was unclear.  The patch in question was in the thread (you
found it more-or-less, I recently CC'd on a "final" version).  It was
not the old 3.2.X-version of config/os/bits/i386/atomicity.h but
rather this new one that correctly uses instructions actually
available on i386.

OK, agreed, but the issue is i386 code compiled on an i386 and then
moved to a higher processor.  OK, someone that explicitly configures
for i386 on an x86-64.  I am still concerned because of this text:

Do I have to do anything special to code against that statement?
