[tor-commits] [torbrowser/master] Patching for mozilla-build. start-msvc.patch will change mozilla-build to use our altered guess-msvc.bat and perform 'make -f client.mk' if a folder is given. guess-msvc-x64.bat is the standard guess-msvc.bat changed to be 64-bit aware. It redirects the registry queries to the required view of the registry.
