#12331: BOOST_FUSION_ADAPT_STRUCT doesn't work with empty struct on Visual Studio

     Type:  Bugs                        |     Status:  new
Milestone:  To Be Determined            |  Component:  fusion
  Version:  Boost 1.61.0                |   Severity:  Problem
 Keywords:                              |
----------------------------------------+---------------------
 The following code works fine on GCC and Clang:

 {{{#!c++
 #include <boost/fusion/adapted/struct/adapt_struct.hpp>

 class EmptyStruct {};

 BOOST_FUSION_ADAPT_STRUCT(EmptyStruct);

 int main() {}
 }}}

 But on Visual Studio 2015 Update 3, it gives the following error:

 {{{
 error C2220: warning treated as error - no 'object' file generated
 warning C4003: not enough actual parameters for macro
 'BOOST_PP_SEQ_DETAIL_IS_NOT_EMPTY'
 warning C4003: not enough actual parameters for macro
 'BOOST_PP_SEQ_DETAIL_EMPTY_SIZE
 }}}
