#13326: linking with program_options has unresolved symbols on MSVC
----------------------------------------+-----------------------------

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?
