Ah, that didn't occur to me.  Duh.  I guess we shall just wait for
libstdc++ to catch up --- it looks like at least some of these issues
are already fixed in GCC CVS.

Even when libstdc++ is updated, we'll still be left with warnings from
C-derived headers, such as the `long long' stuff.  That should be
fixable in some other fashion, but such discussion probably belongs on
freebsd-standards_at_.
