 I was using boost::is_sorted which includes concept library. This gives
 C4510 and C4610 on warning level 4 with vs2008 in the following case:

 {{{
 #include <boost/concept_check.hpp>

 struct Bla
 {
     Bla (int /*i*/)
     {}
 };

 bool operator<(const Bla&, const Bla&)
 {
     return false;
 }

 void f()
 {
    BOOST_CONCEPT_ASSERT((boost::LessThanComparableConcept<Bla>));
 }
 }}}

 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.
