So is it possible to prevent derivation? If not, then at least make it harder to do so (and put a warning in the docs)?

Yes.

Legal way: http://www.research.att.com/~bs/bs_faq2.html#no-derivation

Cool! I have adapted the example to the errorcheck class, so it will report a clean error message. The code has been tested on borland 5.5 and vc-6, vc-7 and vc-7.1 and should work on other compilers. If there is interest, where in the boost-sandbox would be best to put it? My gut feeling is boost/errorcheck.hpp, but if anyone has any better suggestions...
