#11605: Compile errors with Clang 3.7 (and earlier)

 Reporter:  nikkikom@…        |      Owner:  djowel
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  spirit
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:  fusion resule_of  |
------------------------------+---------------------
 The problem is complicated and most probably belongs to 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:
 #if !defined(BOOST_RESULT_OF_USE_DECLTYPE) ||
 defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)

 Should:
 #if 1 || (!defined(BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK) \
   && !defined(BOOST_RESULT_OF_USE_DECLTYPE)) \
     || defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)
