#9538: BOOST_PROTO_USE_NORMAL_RESULT_OF incorrectly defined
-------------------------------+--------------------------
 Reporter:  Hui Li <Hui.Li@…>  |      Owner:  eric_niebler
     Type:  Bugs               |     Status:  new
Milestone:  To Be Determined   |  Component:  proto
  Version:  Boost 1.55.0       |   Severity:  Problem
 Keywords:                     |
-------------------------------+--------------------------
 In proto/proto_fwd.hpp, based on how the macro
 BOOST_PROTO_USE_NORMAL_RESULT_OF is used, it's meant to be defined when
 the compiler supports c++11 decltype and implements N3276, for example,
 BOOST_PROTO_RESULT_OF is boost::result_of when
 BOOST_PROTO_USE_NORMAL_RESULT_OF is defined.

 However, its definition seems incorrect, and is inconsistent with the
 comments next to it.


 {{{

 #ifdef BOOST_NO_CXX11_DECLTYPE_N3276
 ^^^^^^ this should be #ifndef

 # // Proto can only use the decltype-based result_of if N3276 has been
 # // implemented by the compiler.
 # // See http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2011/n3276.pdf

 # ifndef BOOST_PROTO_USE_NORMAL_RESULT_OF
 #  define BOOST_PROTO_USE_NORMAL_RESULT_OF
 # endif
 #endif
