* Removed "warning treated as error" flag from MSVC Setting the "warning treated as error" flag in public projects is problematic, because it can lead to compilation errors for users, when the compiler adds new warnings. This however, does not mean that the project has a bug, only that it emits a new warning. Nevertheless it still fails to compile.
