I don't think this environment variables have any effect on Boost.Build.

Sadly, I don't quite understand what emits the above error message, and I'm not sure this
is 100% verbatim error message either.

MSVC is surely the easiest. Just type:

        bjam --with-thread address-model=64 toolset=msvc install

If you have one version of MSVC and it's installed in default paths, this should work
without any configuration.

For mingw, the right command line would be

        bjam --with-thread address-model=64 toolset=gcc install

However, you would have to setup user-config.jam to point to the right gcc (mingw one,
not cygwin one, at in the right location). See:
