The reason it hasn't been a problem for Apple is that PB wraps
doublequotes around all compiler arguments automatically.  If
this were to get out to people using regular make, there would be
a hue and cry about how their build got mangled (# is special to
make too, after all).

"pound" is somewhat cultural - I think of the char as "sharp" (musical),
and H-P called it "hash".  If we do this, we should use terminology from
the language definition and call it -Wno-warning-directives.
