This gives C4510 and C4610 on warning level 4 with vs2008 in the following case: {{{ #include struct Bla { Bla (int /*i*/) {} }; bool operator<(const Bla&, const Bla&) { return false; } void f() { BOOST_CONCEPT_ASSERT((boost::LessThanComparableConcept)); } }}} I might use it incorrectly; I am not completely sure how to steer this concept library. However it is also easy reproducable with boost::is_sorted(...). The concept_check.hpp already seems to supress these warnings, but maybe the '#pragma pop' is too early."
