Testing Outcome on MSVC, I get:

C:\Users\ned\Downloads\boost_1_71_0_b1_rc1\boost_1_71_0\libs\outcome\test>..\..\..\b2
toolset=msvc-14.0
Performing configuration checks

    - default architecture     : x86

    - BOOST_COMP_GNUC >= 6.0   : no
    - !BOOST_COMP_CLANG        : no
    - BOOST_COMP_CLANG >= 4.0  : no
    - Boost.Config Feature Check: cxx14_variable_templates : yes
    - Boost.Config Feature Check: cxx14_constexpr : yes
    - !BOOST_COMP_GNUC         : no
    - BOOST_COMP_GNUC >= 6.0   : no
    - !BOOST_COMP_CLANG        : no
    - BOOST_COMP_CLANG >= 4.0  : no
    - Boost.Config Feature Check: cxx14_variable_templates : yes
    - Boost.Config Feature Check: cxx14_constexpr : yes
...found 1 target...

Outcome's Jamfile requires:

project
    : requirements
      [ requires cxx14_variable_templates cxx14_constexpr ]
      [ predef-require "!BOOST_COMP_GNUC" or "BOOST_COMP_GNUC >= 6.0" ]
      [ predef-require "!BOOST_COMP_CLANG" or "BOOST_COMP_CLANG >= 4.0" ]
      <define>BOOST_TEST_MODULE=Outcome
      <library>../../test/build//boost_unit_test_framework
    ;

So, the fact that !BOOST_COMP_GNUC and !BOOST_COMP_CLANG are false on
MSVC is a problem, the tests won't run on MSVC.

Yet Outcome works fine for the developer build, as evidenced by the
regression matrix. So this is a problem affecting this release build ONLY.

Thoughts?
