Yes, that was discussed and I hope some solution will be implemented.

Can you try with the attached patch? 

I have a couple of questions though:

1. Dave, I suspect that <runtime-debugging> feature was added by you,
as you authored most of msvc.jam. Maybe, we should rename it to 
<runtime-build> to be compatible with V1.

2. Rene, it looks like "-g" (for runtime-debugging) is added only on Windows.
At least I don't get it on gcc/Linux. But I can't find the logic that 
distinguish between NT and Unix. Can you point me to the code?

Thanks,
Volodya
