This will not work, as 'true' and 'false' are keywords, not macros, in C++ mode, with this compiler. > That will be more portable in > the presence of other platforms with this portability issue. The portability issue is that one of the MSVC headers does basically #ifdef __cplusplus # if defined false || defined true || defined bool || ... # error "..." # endif #endif For the combination of clang with MSVC header files, clang defines _MSC_VER, therefore the workaround should also be effective in this case.
