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 ^^^^^^ should this 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
Am i missing something here?
I agree, that looks suspicious. Is it causing problems? I don't have time to investigate at the moment. Could you please file a bug so I don't lose track of this? Thanks, Eric
