As far as I know, Boost currently provides these definitions for all static member constants that you ask for. If you find one that is missing it should be reported to the author as a bug. If, on the other hand, you use the BOOST_STATIC_CONSTANT macro in your own classes you are of course required to add the definition yourself.
Actually that was my basic assertion and I asked for it correctness. Your first answer implied, that I have to provide that definition on my own (at least for me), this one says otherwise. If you are right, than boost is prepared for every compliant C++ compiler, but (I **assume** again) regrettably not for the currently state-of-the-art Microsoft compiler VC7.1.
Second, your response did not take into account the problems with the effects of the /Ze and /Za flags of the current VC7.1 compiler which I also think is a very important issue.
For that you'll have to ask people who know more about Windows compilers. Since I do not use Windows but just MacOS, Unix and Linux I cannot help with bugs or compiler options of that compiler.
It wasn't meant as an offense, please accept my apologies for my rough tone. Thanks, Daniel
