Building Firefox With Visual C++ Express 2010

I just installed Visual C++ Express 2010 (the most recent version online) in order to build Firefox. However, MozillaBuild has not yet been officially updated to handle Visual C++ 2010. Only 2008 is currently supported as per the build prerequisites. Thankfully, they mention that the trunk version of MozillaBuild should support VC++ Express 2010. The only thing that wasn’t so obvious here (for someone dashing around trying to get building ASAP) was where on earth to look for this. After some totally unnecessary and mostly unhelpful Google-ing around, I ended up at http://hg.mozilla.org/mozilla-build/rev/ad3bd5686474. The necessary start-msvc10.bat and guess-msvc.bat files did the trick.
