I have checked in a boostification/typetraitification of this idea. It can be found in boost/serialization/is_virtual_base_of.hpp
I have tested it as used in the serialization library with MSVC compilers and gcc.
With gcc it doesn't indeed create an annoying warning.
I would like to see the type_trait gurus to:
a) look at this b) see if this gcc warning can be suppressed c) if its OK move it to the type_traits library and out of the serialization librar d) maybe add a separate test. e) and promote to the next release branch since I prefer to run my local tests against the next release branch.
The best way to get the maintainer to look at it is to submit it as a patch attached to a Trac -- David Abrahams BoostPro Computing http://boostpro.com
