Milestone:  To Be Determined            |  Component:  program_options
  Version:  Boost 1.65.0                |   Severity:  Problem

 I'm developing a simple command line client application against
 boost::program_options. Everything works fine on Linux with gcc-4.8,
 gcc-5.3 and gcc-6.3, on Darwin with XCode 7 and on Windows with MinGW-w64.
 But on Windows with MSVC Build Tools 2017 x64 I get two unresolved
 symbols:

 {{{
 LightBISClientCMDLine.cc.obj : error LNK2001: unresolved external symbol
 "class std::basic_string<char,struct std::char_traits<char>,class
 std::allocator<char> > boost::program_options::arg"
 (?arg_at_program_options_at_boost@@3V?$basic_string_at_DU?$char_traits_at_D@std@@V?$allocator_at_D@2@@std@@A)
 LightBISClientCMDLine.cc.obj : error LNK2001: unresolved external symbol
 "public: static unsigned int const
 boost::program_options::options_description::m_default_line_length"
 (?m_default_line_length_at_options_description_at_program_options_at_boost@@2IB)
 }}}

 I checked program_options.dll and I am under the impression that those two
 symbols are defined there. I get exact matches for
 {{{?arg_at_program_options_at_boost@@3V?$basic_string_at_DU?$char_traits_at_D@std@@V?$allocator_at_D@2@@std@@A}}}
 and
 {{{?m_default_line_length_at_options_description_at_program_options_at_boost@@2IB}}}.
 Also all other symbols from program_options are resolved correctly. Here
 is the details build log with a verbose linker message:

 I am explictily setting preprocessor defines for debug, and I set to code
 to build for C++14. Is that possibly related?
