Comment (by Vladimir Prus):

 I am not sure it's a problem with STL classes - the two unresolved
 references are not STL classes, they are static members of program_options
 classes. When building program_options,
 `-DBOOST_PROGRAM_OPTIONS_DYN_LINK=1` must be set, otherwise these two are
 not marked as exported, and this error occurs.

 Commit 1f9413 indeed broke things, but it was then fixed in
 https://github.com/boostorg/boost/commit/a696afede9da8dbf0e3084ad07585148903bfaca

 So, the first step in diagnosing this issue would be to go to
 libs/program_options/build, run `b2 toolset=msvc link=shared -n` and see
 whether the library is built with `-DBOOST_PROGRAM_OPTIONS_DYN_LINK=1` or
 not.
