 // 1) We would prefer to use an enum, but enum values are assignment-
 // compatible with int, which has caused code-generation bugs.
 //
 // 2) We would prefer to use a class instead of a struct but we don't like
 // the register initialization to depend on the particular initialization
 // order (which appears to be different on OS X, Linux, and Windows for the
 // installed versions of C++ we tried). Using a struct permits C-style
 // "initialization". Also, the Register objects cannot be const as this
