says it is impossible to use the prebuilt binaries with Windows xp, however
I manage to use them in Release mode with vc2010, but not in debug mode.
Can this be some indication that there is a tweak to have both the release
and debug version of the libs when built on windows 7 work also for xp?
I would definitely rather use prebuilt openmpi libs as it's easier to change
