-
-// Environment-describing macros
-// -----------------------------
-//
-// Google Test can be used in many different environments. Macros in
-// this section tell Google Test what kind of environment it is being
-// used in, such that Google Test can provide environment-specific
-// features and implementations.
-//
-// Google Test tries to automatically detect the properties of its
-// environment, so users usually don't need to worry about these
-// macros. However, the automatic detection is not perfect.
-// Sometimes it's necessary for a user to define some of the following
-// macros in the build script to override Google Test's decisions.
-//
-// If the user doesn't define a macro in the list, Google Test will
-// provide a default definition. After this header is #included, all
-// macros in this list will be defined to either 1 or 0.
-//
-// Notes to maintainers:
-// - Each macro here is a user-tweakable knob; do not grow the list
-// lightly.
-// - Use #if to key off these macros. Don't use #ifdef or "#if
-// defined(...)", which will not work as these macros are ALWAYS
-// defined.
-//
-// 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
-// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::wstring
-// is/isn't available
-// 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 <pthread.h>
-// 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.
-// GTEST_DEFAULT_DEATH_TEST_STYLE
-// - The default value of --gtest_death_test_style.
-// The legacy default has been "fast" in the open
-// source version since 2008. The recommended value
-// is "threadsafe", and can be set in
-// custom/gtest-port.h.
-
-// Platform-indicating macros
-// --------------------------
-//
-// Macros indicating the platform on which Google Test is being used
-// (a macro is defined to 1 if compiled on the given platform;
-// otherwise UNDEFINED -- it's never defined to 0.). Google Test
-// defines these macros automatically. Code outside Google Test MUST
-// NOT define them.
-//
-// GTEST_OS_AIX - IBM AIX
-// GTEST_OS_CYGWIN - Cygwin
-// GTEST_OS_FREEBSD - FreeBSD
-// GTEST_OS_FUCHSIA - Fuchsia
-// GTEST_OS_HPUX - HP-UX
-// GTEST_OS_LINUX - Linux
-// GTEST_OS_LINUX_ANDROID - Google Android
-// GTEST_OS_MAC - Mac OS X
-// GTEST_OS_IOS - iOS
-// GTEST_OS_NACL - Google Native Client (NaCl)
-// GTEST_OS_NETBSD - NetBSD
-// GTEST_OS_OPENBSD - OpenBSD
-// GTEST_OS_QNX - QNX
-// GTEST_OS_SOLARIS - Sun Solaris
-// GTEST_OS_SYMBIAN - Symbian
-// GTEST_OS_WINDOWS - Windows (Desktop, MinGW, or Mobile)
-// GTEST_OS_WINDOWS_DESKTOP - Windows Desktop
-// GTEST_OS_WINDOWS_MINGW - MinGW
-// GTEST_OS_WINDOWS_MOBILE - Windows Mobile
-// GTEST_OS_WINDOWS_PHONE - Windows Phone
-// GTEST_OS_WINDOWS_RT - Windows Store App/WinRT
-// 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
-// googletestframework@googlegroups.com (patches for fixing them are
-// even more welcome!).
-//
-// It is possible that none of the GTEST_OS_* macros are defined.
-
-// Feature-indicating macros
-// -------------------------
-//
-// Macros indicating which Google Test features are available (a macro
-// is defined to 1 if the corresponding feature is supported;
-// otherwise UNDEFINED -- it's never defined to 0.). Google Test
-// defines these macros automatically. Code outside Google Test MUST
-// NOT define them.
-//
-// These macros are public so that portable tests can be written.
-// Such tests typically surround code using a feature with an #if
-// which controls that code. For example:
-//
-// #if GTEST_HAS_DEATH_TEST
-// EXPECT_DEATH(DoSomethingDeadly());
-// #endif
-//
-// GTEST_HAS_COMBINE - the Combine() function (for value-parameterized
-// tests)
-// GTEST_HAS_DEATH_TEST - death tests
-// GTEST_HAS_TYPED_TEST - typed tests
-// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
-// GTEST_IS_THREADSAFE - Google Test is thread-safe.
-// GOOGLETEST_CM0007 DO NOT DELETE
-// 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 RE\b(s) are mutually exclusive.
-// GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
-
-// Misc public macros
-// ------------------
-//
-// GTEST_FLAG(flag_name) - references the variable corresponding to
-// the given Google Test flag.
-
-// Internal utilities
-// ------------------
-//
-// The following macros and utilities are for Google Test's INTERNAL
-// use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
-//
-// Macros for basic C++ coding:
-// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
-// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
-// variable don't have to be used.
-// GTEST_DISALLOW_ASSIGN_ - disables operator=.
-// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
-// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
-// GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
-// suppressed (constant conditional).
-// GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
-// is suppressed.
-//
-// C++11 feature wrappers:
-//
-// testing::internal::forward - portability wrapper for std::forward.
-// testing::internal::move - portability wrapper for std::move.
-//
-// Synchronization:
-// Mutex, MutexLock, ThreadLocal, GetThreadCount()
-// - synchronization primitives.
-//
-// 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:
-// RE - a simple regular expression class using the POSIX
-// Extended Regular Expression syntax on UNIX-like platforms
-// GOOGLETEST_CM0008 DO NOT DELETE
-// or a reduced regular exception syntax on other
-// platforms, including Windows.
-// Logging:
-// GTEST_LOG_() - logs messages at the specified severity level.
-// LogToStderr() - directs all log messages to stderr.
-// FlushInfoLog() - flushes informational log messages.
-//
-// Stdout and stderr capturing:
-// CaptureStdout() - starts capturing stdout.
-// GetCapturedStdout() - stops capturing stdout and returns the captured
-// string.
-// CaptureStderr() - starts capturing stderr.
-// GetCapturedStderr() - stops capturing stderr and returns the captured
-// string.
-//
-// Integer types:
-// TypeWithSize - maps an integer to a int type.
-// Int32, UInt32, Int64, UInt64, TimeInMillis
-// - integers of known sizes.
-// BiggestInt - the biggest signed integer type.
-//
-// Command-line utilities:
-// GTEST_DECLARE_*() - declares a flag.
-// GTEST_DEFINE_*() - defines a flag.
-// GetInjectableArgvs() - returns the command line as a vector of strings.
-//
-// Environment variable utilities:
-// GetEnv() - gets the value of an environment variable.
-// BoolFromGTestEnv() - parses a bool environment variable.
-// Int32FromGTestEnv() - parses an Int32 environment variable.
-// StringFromGTestEnv() - parses a string environment variable.

-// - The simpler definition
-//
-// #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]
-//
-// does not work, as gcc supports variable-length arrays whose sizes

-//
-// int foo;
-// GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is
-// // not a compile-time constant.
-//
-// - By using the type CompileAssert<(bool(expr))>, we ensures that
-// expr is a compile-time constant. (Template arguments must be
-// determined at compile-time.)
-//
-// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
-// to work around a bug in gcc 3.4.4 and 4.0.1. If we had written
-//
-// CompileAssert<bool(expr)>
-//
-// instead, these compilers will refuse to compile

-// GTEST_COMPILE_ASSERT_(5 > 0, some_message);

-// - The array size is (bool(expr) ? 1 : -1), instead of simply
-//
-// ((expr) ? 1 : -1).
