Compiling itself already uses multi cores, but other stuff is still on single core. This patch enables that by passing an argument to MSBuild.exe.

I THINK the environment variable checked above should be set on windows. There looks to be a perl module that will tell you the number of CPUs as well http://search.cpan.org/~burak/Sys-Info-Base-0.7802/lib/Sys/Info/Device/CPU.pm which sounds like it calls into WMI
