Thanks will fix - I've got a bunch of other really exciting changes comming
(licence scanning) - so the patch may have to wait a few days.

Or maybe it should just go ahead and overwrite, should be easy to fix.

Hmm, it seems to pull in more of type_traits than I would have expected, and
that pulls in part of mpl, and then a whole load of the preprocessor
library.  I don't think any given compiler will include half of that, but
which half depends upon which compiler...
