And, in the proposed memory model, I believe we have one.  If there is
some reason you believe the proposed memory model won't be sufficient,
then maybe we can start looking at doing something gcc local.  But it
would surely be much better to do this through the ISO TC.  They will
doubtless be glad to respond to any concerns that you have.

Andrew.
