    Visual Studio 2008 Builds: Speed Up Release Builds
    
    Use the /MP option so that each project can build multiple sources in
    parallel, which can cut down release build times by quite a bit.  This will
    cause a brief warning for debug builds due to their use of /Gm, and builds
    would otherwise proceed as they did before.
    
    Unfortunately Visual Studio 2008 is too old to support the /d2Zi+ flag, so
    we can't make a better debug situation for it at the moment.
