3501	Reusing concepts from different compile units yields multiple defined symbols	christoph.heindl@…	Gunter	"Currently I use the ublas concepts defined in ublas/detail/concepts.hpp to derive concepts based on ublas concepts such as

template<class X>
struct Vector : boost::numeric::ublas::VectorConcept<X> 
{};

In my unit test project I have different compile units that use BOOST_CONCEPT_ASSERT to assure Vector concept compliance. This yields multiple defined symbols for the following methods (and full specialized versions):

ublas/detail/concepts.hpp:
void concept_checks();
template<class T> ZeroElement(T);
template<class T> OneElement(T);

inlining those solves the problem (for me). I'm compiling on MSVC9.0. Current trunk seems to have this methods still not-inlined."	Bugs	closed	Boost 1.41.0	uBLAS	Boost 1.39.0	Problem	fixed
