Using the MSVC compiler, an instance of an enum type with value zero, is compatible with void* (see bug 132683 for a code example). This has caused crashes on Windows on two occasions (bug 132683, and bug 121001). This patch tries to prevent these type of crashes by using a type with explicit constructors instead of void*.
