// This file defines common macros that are used in protobuf.
//
// To hide these definitions from the outside world (and to prevent collisions
// if more than one version of protobuf is #included in the same project) you
// must follow this pattern when #including port_def.inc in a header file:
//
// #include "other_header.h"
// #include "message.h"
// // etc.
//
// #include "port_def.inc"  // MUST be last header included
//
// // Definitions for this header.
//
// #include "port_undef.inc"
//
// This is a textual header with no include guard, because we want to
// detect/prohibit anytime it is #included twice without a corresponding
// #undef.

// The definitions in this file are intended to be portable across Clang,
// GCC, and MSVC. Function-like macros are usable without an #ifdef guard.
// Syntax macros (for example, attributes) are always defined, although
// they may be empty.
