On the other hand, there's often more than one way to skin a cat.
It occurred to me that maybe we could just turn off this class of warning,
and after some experimentation I found out that
"-Wno-unused-command-line-argument" does that, at least in the version
of clang that Apple's currently shipping.
Who's for enabling that if the compiler takes it?
