I don't know what you mean.

I don't know what that means either.

So, if not via test_tools.hpp, then how does it end up in that
translation unit?

Although if your claim is true (that unit_test_parameters.ipp isn't included by
test_tools.hpp) that's irrelevant.

That's because you're not a human Jam interpreter. It's in there.

So download it. It takes about ten seconds over a fast connection.
Or don't, if you don't want to look at this problem.

But my question remains: why is that function in a header when it
could be compiled into the library? Seems pretty inefficient, at
least for Boost, which runs many many tests using your library, to
compile that function body over and over.
