You shouldn't ever see those messages - they're produced as part of the
Jamfile's configuration process. The only time I'm aware of when they
show up is if you invoke bjam from inside the Visual Studio IDE - in
that case the IDE captures cl compiler output before bjam gets to see
it. I think there may be an environment variable that controls that,
but I'm not sure.

And no, there's no way to explicitly disable the configure-checks.

Yes, all the tests on the cpp_int cpp_dec_float and cpp_bin_float backends.
