OK, I see the issue: there is a cyclic dependency, however all the other compilers for which we can implement is_abstract we also define BOOST_TT_HAS_CONFORMING_IS_CLASS_IMPLEMENTATION which neatly avoids the cyclic dependency.

This works perfectly. Thanks for the tip.

Didn't we decide that flags for conformance should always be in the form of BOOST_NO_some-conforming-c++-feature so that unless something special is done, the assumption will be that the compiler conforms? -- Dave Abrahams Boost Consulting www.boost-consulting.com
