In MSVC 6.0, the following snippet fails:

complaining about is_abstract being already defined. The problem lies in the following lines inside boost/serialization/is_abstract.hpp:> #ifndef BOOST_TT_IS_ABSTRACT_CLASS_HPP #if defined(__GNUC__) && (34 <= _GNUC__ * 10 + __GNU_MINOR) \ || defined(__MSVC_VER) && (1310 <= __MSVC_VER) \ || defined(__EDG_VERSION__) \ /**/ #include <boost/type_traits/is_abstract.hpp> #else

First of all, the whole thing is a huge hack and can cause an ODR violation on 1-2-3. We should really fix type_traits to fall back to something like the code below, but that is definitely out for the release.

Yep, I'll take care of this as soon as Boost 1.32 is out -I need it for my own purposes :)

Having said that, the #else branch is simply missing this:

# define BOOST_TT_IS_ABSTRACT_CLASS_HPP

[...]

...

If nobody complains, I can fix this and commit it to the release and main branch.

Please! Together with the #define, if you can.
