On my first time attempt building Firefox I received this error. I thought that my C++ compiler wasn't working and tried installing one and adding it to my path. No success.

After stumbling around the net for a while someone wrote "Use the command window from Visual Studio". I didn't think of that all for some reason. When I opened command prompt from visual studio I got past this error. By using that command window I guess I was referencing my Visual Studio copy of C++ which the build could understand.
