To be more precise, include directives must use angle brackets and be relative
to the Boost root directory, i.e. look like

Correct! Unfortunately the issue with truncated test output made it look like
tests were running without problems.

Note that once this issue is corrected, we'll be faced with the static linking
problem I mentioned on the Boost Build mailing list. This is currently causing
almost all the serialization static linking tests to fail.

Fine by me.
