[boost] [parameter] Macro for CodeGear SFINAE problems (answering Dave's comment)

Dave wrote in a Ticket comment:

OK, then if you can find the time, I would prefer then to have another configuration macro (parameter-library-specific if no other libs need it) for this purpose. Code repetition is evil, even PP code.

[I'm moving this discussion: http://svn.boost.org/trac/boost/ticket/1305 to the mailing list, as it seems more appropriate.] Where you thinking of something like BOOST_CODEGEAR_SFINAE_BUG? If so, I'll look into it. Cheers, Nicola Musatti
