Hallo, Much to my dismay I realized this morning that I left the following patch behind: http://svn.boost.org/trac/boost/attachment/ticket/2346/boost_type_traits.pat... I'm fully aware that it is rather extensive to be applied this late in the cycle. However it is specific to Borland/CodeGear and has gone through a few test cycles on trunk without causing problems. Unfortunately due to the fundamental role that the type_traits library plays in the implementation of many other libraries, without this patch most of the other Borland/CodeGear related ones have no effect. I discussed this with John Maddock and he agreed to perform the merge if I obtained your permission.
