Re: [boost] is_enum andis_convertibleinterdependencies....BOOST_NO_IS_ABSTRACT

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?

Absolutely: however BOOST_TT_HAS_CONFORMING_IS_CLASS_IMPLEMENTATION was one of yours I believe: chuckles, ducks, runs for cover.... John.
