As you seem to build the Boost Libraries "offline" you could modify the 
project definition inside the Jamroot (if you are ok with hacking the 
Jamroot):

project boost
        : requirements
        ...
        <toolset>msvc:<define>_CRT_SECURE_NO_DEPRECATE
        <toolset>msvc:<define>_SCL_SECURE_NO_DEPRECATE
        <toolset>msvc:<define>_HAS_ITERATOR_DEBUGGING=0
        <toolset>msvc:<define>_CRT_NONSTDC_NO_DEPRECATE
        <toolset>msvc:<define>_SECURE_SCL=0
        ...
        ;

Then use Boost.Build to rebuild the libraries. Use "bjam -a ..." as the 
above won't trigger rebuilds if you've already built the stuff once using 
Boost.Build (contradicted by your statements above, but just to make sure).
