And I don't have it there since I tested on an old version of FreeBSD.

Not gcc-4.2?  gcc-3.4.6 is also for an old (but latest released) version
of FreeBSD.  Maybe all the __pure's added to <string.h> actually have an
effect only with gcc-4.

It means both, and I think it is in more common use for alpha, but
alpha is dead :-).  Common use seems to be to spell out "Athlon [tm]",
probably for marketing reasons, but the chips are labeled AXP and that
is easier to type, so I use it a lot.
