Fine, for now.

Thanks, Ill try that.

They continue to apply until changed. But the better way to disable is to push
and pop as Reece Dunn recently proposed. I have recently suggested that we need
a Boost 'Standard' way of doing this, and agreement on what warnings should be
disabled routinely (in Boost config perhaps).

This is the Really Right Thing to DO, of course :-)
(Reece (?) also recently suggested deriving
class YourClass :: public boost::noncopyable
and this worked for me on one example.

Looks OK to me but perhaps someone can run it past one of these strange

I look forward to this.
