Actually, I am instead preparing to take this up with the standards
committee.  Even those who hate volatile (of which there are many) have
an interest in a good codification of the defacto definition of volatile.
After all, without a definition how can they hope to replace it?  ;-)
And the C committee cares deeply about backwards compatibility, so
getting a good definition will help there as well.
