//
// Note that even though _MSC_VER and _WIN32_WCE really indicate a compiler
// and a Win32 implementation, respectively, we use them to indicate the
// combination of compiler - Win 32 API - C library, since the code currently

// Windows proper with Visual C++ and MS C library (_MSC_VER && !_WIN32_WCE) and
// Windows Mobile with Visual C++ and no C library (_WIN32_WCE).

// Depending on the platform, different string classes are available.
// On Windows, ::std::string compiles only when exceptions are
// enabled. On Linux, in addition to ::std::string, Google also makes
// use of class ::string, which has the same interface as
// ::std::string, but has a different implementation.
//
// The user can tell us whether ::std::string is available in his
// environment by defining the macro GTEST_HAS_STD_STRING to either 1
// or 0 on the compiler command line. He can also define
// GTEST_HAS_GLOBAL_STRING to 1 to indicate that ::string is available
// AND is a distinct type to ::std::string, or define it to 0 to
// indicate otherwise.
//
// If the user's ::std::string and ::string are the same class due to
// aliasing, he should define GTEST_HAS_STD_STRING to 1 and
// GTEST_HAS_GLOBAL_STRING to 0.
//
// If the user doesn't define GTEST_HAS_STD_STRING and/or
// GTEST_HAS_GLOBAL_STRING, they are defined heuristically.
