Oooh.
[ Raises hand, and says "I know, I know, pick me, pick me" ]
min_not_zero() hasinternal variables "__x" and "__y".
And "__cmp_once()" has internal variables "__x" and "__y".
When min_not_zero does
min(__x, __y));
that expands to crazy stuff.
Out old "min()" had the internal variables called "min1" and "min2",
which is crazy too.
