Well, if you're not yet 40, of *course* you're partially ignorant, but I'd
never ever accuse you of being lazy <wink>.  I surely appreciate all the
good work you're doing here!  At the same time, I want everyone to realize
that the 64-bit world isn't equal to Win84, and we've got to watch out for
all *sorts* of stuff (for example, a bit of the code in longobject.c is
broken on the 64-bit Cray J90 in ways that aren't broken under Win64; for
example, the J90 has the only C compiler I've ever heard of where right
shifts of signed integral types do *not* extend the sign bit -- which is
fine by ANSI, but catches some of Python's internals by surprise).
