8844	[PATCH] arg.hpp should use BOOST_STATIC_ASSERT	pmachata@…	Peter Dimov	"template <int I> template<class T> boost::arg<I>::arg<T> (T &) contains code equivalent to BOOST_STATIC_ASSERT:
{{{
        // static assert I == is_placeholder<T>::value
        typedef char T_must_be_placeholder[ I == is_placeholder<T>::value? 1: -1 ];
}}}

GCC recently added a warning for this unused typedef case.  This can be worked around by adding __attribute__ ((__unused__)), but why not simply use BOOST_STATIC_ASSERT?

Test suite passes."	Patches	closed	To Be Determined	bind	Boost 1.54.0	Problem	fixed
