#11606: Compile errors with Clang 3.7 (and earlier)

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  spirit
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 The problem is complicated and most probably belongs to **Boost.Fusion**.
 However I'm not very sure, and technically all tests from fusion compile,
 it's the test from spirit repository fails. So, I'm posting it under the
 spirit component.

 The spirit/repository/test/qi/keywords.cpp does not compile with recent
 clang_at_apple with default preprocessor definitions. I'm attaching the
 compiler log with this ticket.

 The only way I can compile it is to use
 **BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK** preprocessor flag,
 unfortunately with flags triggers another branch of compile errors related
 to **fusion's result_of** helper. To fix
 **BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK** compile errors the file
 boost/fusion/support/detail/result_of.hpp should be modified as follows:

 Was:
 {{{
 #!c++
 #if !defined(BOOST_RESULT_OF_USE_DECLTYPE) ||
 defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)
 }}}
 Should:
 {{{
 #!c++
 #if 1 || (!defined(BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK) \
   && !defined(BOOST_RESULT_OF_USE_DECLTYPE)) \
     || defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)
 }}}
