Would adding the MSVC *_SECURE_* defines to NOT deprecate the 'insecure' version
help?

 project  
    : requirements  

      #  The define of macros below prevent warnings about the checked versions
of SCL and CRT libraries.
      #  Most Boost code does not need these versions (as they are markedly
slower).
      <toolset>msvc:<define>_SCL_SECURE_NO_WARNINGS
      <toolset>msvc:<define>_SCL_SECURE_NO_DEPRECATE
      <toolset>msvc:<define>_CRT_SECURE_NO_WARNINGS
      <toolset>msvc:<define>_CRT_SECURE_NO_DEPRECATE

      #  Alternatively, you can just suppress the warnings (probably not the
best way).
      <toolset>msvc:<cxxflags>/wd4996 # 'putenv': The POSIX name for this item
is deprecated. (and other similar deprecations).
;

As suggested in

https://svn.boost.org/trac/boost/wiki/Guidelines/MaintenanceGuidelines

This may also deal with the "unsafe"?
