Or, more precisely, "because it's been useful."

The pointer<->integer size-change warnings show up without -Wall, then
they are appropriate.  In general, on the alpha, every one of those
warnings needs to be inspected and fixed as if it's a bug, because a
non-trivial fraction of them are.  8-)

So, it's been useful in the past to have 'make' error about them, and
(when the code changes) continues to be useful.
