// This header includes macros that can end up being dragged into
// the generated code from system headers, such as major() or NDEBUG.
// If a Slice symbol has the same name as a macro, the generated
// code most likely won't compile (but, depending how the macro is
// defined, may even compile).
//
// Here, we undefine symbols that cause such problems.
//
// The #ifdef ... #endif protection is necessary to prevent
// warnings on some platforms.
