Well, probably because no one (at least not me or Kai) knew about this. I
presume libstdc++ or gcc/g++ configure is missing this step in the case of
posix threading on Windows. Kai, could you look into this? Perhaps a
similar issue could be causing the weird OpenMP crash we don't have a test
case for?

I have verified your build works fine indeed. Thanks niXman! Please don't
leave the people who can actually fix this in the dark. Not a lot GCC devs
care about Windows. I would hazard a guess Kai here writes ~30-50% of the
Windows GCC patches ;-)

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
