That way vc6 is still supported subject to the header ordering
restriction while for other compilers the restriction is eliminated.
Since the old code is already written and tested, there is no
cost to doing this. It also provides an "escape hatch" should
we come upon some other compiler that can't handle the
I'll be curious to see how you did this. I did spend a lot
of time trying to find a better solution. I'm also curious
to see if it solves some code instantiation failures with
