It is a lot of work to gain even a moderately deep understanding of
bjam, but if you treat it like magic, some of the simpler incantations
are very easy to learn. compile-fail tests fall in the simple
category.

In https://svn.boost.org/svn/boost/sandbox/chrono, take a look at
libs/chrono/test/Jamfile.v2 and ratio_fail_test1.cpp.

If I run "bjam --toolset gcc", note that the test is reported as
"**passed**", because there were compile errors.

Temporarily change ratio_fail_test1.cpp so that the ratio multiply
doesn't overflow, and the compile will work but the test will be
reported as failing
