I've just retested iterator_adaptors_test with is_convertible.hpp at
version 1.18 (pre-patch) and version 1.21 (the current HEAD). Both are

The only thing I can think that this could mean is that some other factor,
such as the toolset or a compiler service pack, is affecting the results.

I'll try the full regression tests against 1.18 to see what would happen if
we rolled back the Intel changes. I'll report results as soon as the run

I think only tests which failed were those dependent on the iterators

John Maddock added those about version 1.8. I don't know why.
