  Version:  Boost 1.67.0      |   Severity:  Problem

------------------------------+---------------------
 Cannot link to boost_python correctly. Using MSVC 2015 Update 3,
 boost_1_67_0\boost\python\detail\config.hpp line 108 does not expand as
 intended:

 (line 108) #define BOOST_LIB_NAME
 boost_python##PY_MAJOR_VERSION##PY_MINOR_VERSION

 This line expands to
 "boost_pythonPY_MAJOR_VERSIONPY_MINOR_VERSION(...).lib", which results in
 a linking error since the library is named "boost_python36(...).lib"

 My Python distribution is Anaconda 5.1 and patchlevel.h has:

 (line 19) #define PY_MAJOR_VERSION      3

 (line 20) #define PY_MINOR_VERSION      6

 Similarly, one will have difficulty with
 boost_1_67_0\boost\python\numpy\config.hpp line 64.

 I tried repeatedly to make the preprocessor directives work as intended
 but I cannot quite figure it out. I wish I could find where the library
 name is generated for the build, not just the link.
