That---in particular the lattermost clause---is true of `volatile'; it
is not true of `noalias', at least as it was conceived and proposed.
It could only be ignored when not used, not even by library routines
called by routines called by you.  Having been through the arguments
before, I intend to omit them this time around and simply leave the
statement at that.
