Considering how different versions of Visual Studio sometimes require
different settings, and their compilers issue different warnings, we
set TreatWarningAsError to false to avoid unforeseen and undesirable
build failures for the users who upgrade to a newer Visual Studio that
might bring along a more pedantic compiler:
