| // ::string, which is different to std::string). |
| // GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string |

| // ::wstring, which is different to std::wstring). |
| // GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h> |

| // This header defines the following utilities: |
| // |
| // Macros indicating the current platform (defined to 1 if compiled on |

| // even more welcome!). |
| // |
| // Note that it is possible that none of the GTEST_OS_* macros are defined. |
| // |
| // Macros indicating available Google Test features (defined to 1 if |
| // the corresponding feature is supported; otherwise undefined): |
| // GTEST_HAS_COMBINE - the Combine() function (for value-parameterized |

| // GTEST_HAS_DEATH_TEST - death tests |
| // GTEST_HAS_PARAM_TEST - value-parameterized tests |
| // GTEST_HAS_TYPED_TEST - typed tests |
| // GTEST_HAS_TYPED_TEST_P - type-parameterized tests |
| // GTEST_USES_POSIX_RE - enhanced POSIX regex is used. |
| // GTEST_USES_SIMPLE_RE - our own simple regex is used; |

| // |
| // Macros for basic C++ coding: |
| // GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning. |

| // variable don't have to be used. |
| // GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=. |
| // GTEST_MUST_USE_RESULT_ - declares that a function's result must be used. |
| // |
| // 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. |
| // |
| // Smart pointers: |
| // scoped_ptr - as in TR2. |
| // |
| // Regular expressions: |
| // RE - a simple regular expression class using the POSIX |
| // Extended Regular Expression syntax. Not available on |
| // Windows. |
| // |
| // Logging: |
| // GTEST_LOG_() - logs messages at the specified severity level. |
| // LogToStderr() - directs all log messages to stderr. |
| // FlushInfoLog() - flushes informational log messages. |
| // |
| // Stderr capturing: |
| // CaptureStderr() - starts capturing stderr. |

| // string. |
| // |
| // Integer types: |
| // TypeWithSize - maps an integer to a int type. |

| // |
| // Environment variable utilities: |
| // GetEnv() - gets the value of an environment variable. |
