Careful, here -- they did! Well, that is one with a higher version number ;-)

Latest official BCC shipped with BuilderX:

    __BORLANDC__ == 0x565

Latest Builder6 upgrade pack:

    __BORLANDC__ == 0x564

Kylix (didn't verify it myself - source: Boost.Config):

    __BORLANDC__ == 0x570

It seems all are pretty close in terms of portability (for the former two I know 
it and for Kylix it's another guess reading Boost.Config), so testing for below 
0x600 is what you want, I guess (and above 0x551, reading the follow-up).
