[Boost-build] <asynch-exceptions>on cannot be specified in usage-requirements

The test library specifies in its requirements:

<toolset>msvc:<asynch-exceptions>on

Now when I try to put this also into the usage-requirements, and try to 
build something that uses the test library Boost.Build complains with:

error: usage-requirements <toolset>msvc:<asynch-exceptions>on have 
non-free properties <asynch-exceptions>on

So my question is, how to solve this?

The test lib author told me, mixing of synch and synch (the default) is 
"plain wrong".

Please help!
