    MSVC 2008 Builds: Speed Up Release Builds
    
    Use the /MP compiler option, where the build time for release builds can
    be cut down by quite a bit.  This will however cause a brief warning with
    debug builds due to the use of /Gm, but the code will otherwise build
    normally.  Unlike the Visual Studio 2010+ builds, we can't use /d2Zi+ as
    Visual Studio 2008 does not support that, so we can't get a better
    debugging experience for release builds here.
