This can cause GTEST_HAS_EXCEPTIONS to be defined incorrectly if the user has disabled exceptions via the compiler, which can lead to build errors. _CPPUNWIND is a builtin macro provided by the compiler so it should work with both STLs. --- googletest/include/gtest/internal/gtest-port.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/googletest/include/gtest/internal/gtest-port.h b/googletest/include/gtest/internal/gtest-port.h index 01ad5dac..1a1d9dd0 100644 --- a/googletest/include/gtest/internal/gtest-port.h +++ b/googletest/include/gtest/internal/gtest-port.h @@ -464,8 +464,11 @@ typedef struct _RTL_CRITICAL_SECTION GTEST_CRITICAL_SECTION; #ifndef GTEST_HAS_EXCEPTIONS // The user didn't tell us whether exceptions are enabled, so we need // to figure it out. -# if defined(_MSC_VER) || defined(__BORLANDC__) -// MSVC's and C++Builder's implementations of the STL use the _HAS_EXCEPTIONS +# if defined(_MSC_VER) && defined(_CPPUNWIND) +// MSVC defines _CPPUNWIND to 1 iff exceptions are enabled. +# define GTEST_HAS_EXCEPTIONS 1 +# elif defined(__BORLANDC__) +// C++Builder's implementation of the STL uses the _HAS_EXCEPTIONS // macro to enable exceptions, so we'll do the same. // Assumes that exceptions are enabled by default. # ifndef _HAS_EXCEPTIONS
