On combining #import and /MP in C++ builds with VS2010

I’m currently busy porting a large native C++ project from VS2008 to VS2010 and one of the issues I keep running into was build times. The VS2008 build uses a distributed build system; Unfortunately the vendor doesn’t support VS2010 yet, so I couldn’t use the same infrastructure. In order to get a decent build speed, I started exploring MSBuild’s ability to build projects in parallel (which is fairly similar to VS2008’s ability to build projects in parallel) and the C++ compiler’s ability to make use of multiple processors/cores, aka the /MP switch.
