// Objective C++ can run into issues with how the NS_ENUM/CF_ENUM declaration
// works because of the C++ spec being used for that compilation unit. So
// the fact that these imports all work without errors/warning means things
// are still good.
//
// The "well know types" should have cross file enums needing imports.
#import "GPBProtocolBuffers.h"
// Some of the tests explicitly use cross file enums also.

  // define in GPBBootstrap.h.
