// The user can define the following macros in the build script to
// control Google Test's behavior. If the user doesn't define a macro
// in this list, Google Test will define it.
//
// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
// is/isn't available.
// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
// are enabled.
// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
// is/isn't available (some systems define
// ::string, which is different to std::string).
// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
// is/isn't available (some systems define
// ::wstring, which is different to std::wstring).
// GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
// expressions are/aren't available.
// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that
// is/isn't available.
// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
// enabled.
// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
// std::wstring does/doesn't work (Google Test can
// be used where std::wstring is unavailable).
// GTEST_HAS_TR1_TUPLE - Define it to 1/0 to indicate tr1::tuple
// is/isn't available.
// GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
// compiler supports Microsoft's "Structured
// Exception Handling".
// GTEST_HAS_STREAM_REDIRECTION
// - Define it to 1/0 to indicate whether the
// platform supports I/O stream redirection using
// dup() and dup2().
// GTEST_USE_OWN_TR1_TUPLE - Define it to 1/0 to indicate whether Google
// Test's own tr1 tuple implementation should be
// used. Unused when the user sets
// GTEST_HAS_TR1_TUPLE to 0.
// GTEST_LANG_CXX11 - Define it to 1/0 to indicate that Google Test
// is building in C++11/C++98 mode.
// GTEST_LINKED_AS_SHARED_LIBRARY
// - Define to 1 when compiling tests that use
// Google Test as a shared library (known as
// DLL on Windows).
// GTEST_CREATE_SHARED_LIBRARY
// - Define to 1 when compiling Google Test itself
// as a shared library.
// This header defines the following utilities:
//
// Macros indicating the current platform (defined to 1 if compiled on
// the given platform; otherwise undefined):
// GTEST_OS_AIX - IBM AIX
// GTEST_OS_CYGWIN - Cygwin

// GTEST_OS_ZOS - z/OS
//
// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
// most stable support. Since core members of the Google Test project
// don't have access to other platforms, support for them may be less
// stable. If you notice any problems on your platform, please notify
// [email protected] (patches for fixing them are
// even more welcome!).
//
// Note that it is possible that none of the GTEST_OS_* macros are defined.

// GTEST_HAS_TYPED_TEST - typed tests
// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
// GTEST_HAS_POSIX_RE (see above) which users can
// define themselves.
// GTEST_USES_SIMPLE_RE - our own simple regex is used;
// the above two are mutually exclusive.

//
// Synchronization:
// Mutex, MutexLock, ThreadLocal, GetThreadCount()
// - synchronization primitives.
// GTEST_IS_THREADSAFE - defined to 1 to indicate that the above
// synchronization primitives have real implementations
// and Google Test is thread-safe; or 0 otherwise.
//
// Template meta programming:
// is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.
// IteratorTraits - partial implementation of std::iterator_traits, which
// is not available in libCstd when compiled with Sun C++.
//
// Smart pointers:
// scoped_ptr - as in TR2.
//
// Regular expressions:

// its way into the language in the future.

// namespace alone is not enough because the function can be found by ADL.

// When you upcast (that is, cast a pointer from type Foo to type
// SuperclassOfFoo), it's fine to use ImplicitCast_<>, since upcasts
// always succeed. When you downcast (that is, cast a pointer from
// type Foo to type SubclassOfFoo), static_cast<> isn't safe, because
// how do you know the pointer is really of type SubclassOfFoo? It
// could be a bare Foo, or of type DifferentSubclassOfFoo. Thus,
// when you downcast, you should use this macro. In debug mode, we
// use dynamic_cast<> to double-check the downcast is legal (we die
// if it's not). In normal mode, we do the efficient static_cast<>
// instead. Thus, it's important to test in debug mode to make sure
// the cast is legal!
// This is the only place in the code we should use dynamic_cast<>.
// In particular, you SHOULDN'T be using dynamic_cast<> in order to
// do RTTI (eg code like this:
// if (dynamic_cast(foo)) HandleASubclass1Object(foo);
// if (dynamic_cast(foo)) HandleASubclass2Object(foo);
// You should design the code some other way not to need this.
