I just tried statically linked single-threaded builds and...they work.
 I thought I had done this already, but I guess I hadn't.  (also, I
just checked, and so does the multi-threaded static build).   Oh man.

Warms thanks for your assistance (also to Volodya also).

For the sake of completeness, and because I had it all written any
way, here's my response to the rest of your email.

I've tried linking to a variety of different libraries in a variety of
different build modes.

It ran the test, with both (toolset=msvc and toolset=gcc), and both passed.

Tried catching it with

   catch ( std::runtime_error ex  )

and

        catch ( boost::filesystem::filesystem_error ex )

but neither catch anything.

create_directory() and exists() work fine, but remove_all() seems to
throw a similar error.

I can get it to throw this error the release build as well.
