#8844: [PATCH] arg.hpp should use BOOST_STATIC_ASSERT

     Type:  Patches           |     Status:  new
Milestone:  To Be Determined  |  Component:  bind
  Version:  Boost 1.54.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 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.
