Totally agree.

I would need to detect support for std::current_exception, not the presence
of header <exception>, so I would think that
BOOST_NO_CXX11_CURRENT_EXCEPTION is what I need, right?

So that I can
// I can use std::current_exception() unconditionally here

Should I open an issue in github for Boost.Config?
