Nathan Ridge and I made some efforts to test compatibility with
decltype-based result_of. All the incompatibilities we found were just
introduced by the incorrect use of result_of. They were not related to N3276.

IIRC, Pointer Container, Fusion and Spirit were fixed,
but Phoenix is still in the fixing process.

It's pretty easy for me to report the results of testing with
decltype-based result_of, when the test runs successfully.
But, when the test fails, it is not a trivial task for me to check
whether the failure is actually caused by decltype-based result_of :/
(Of course, if someone requests testing with decltype-based result_of
for a specific library, I'll try to test it :-) )

I think modifying Jamfile to add the test with decltype-based result_of
is a reasonable approach to the regression tests.
