I've no idea frankly *why* the compiler finds those types, but it certainly
does do so - please take a look at the reduced test case in the bug report.
I forget the namespace lookup rules now, but could your enable_if be in an
associated namespace (the namespace of the base class of the unit test case)
that gets searched during name lookup? Either way I believe in the long run
we won't be the only ones hit by this, so I think it should be fixed in
Boost.Test. Renaming those types seems like the easiest option?
