On the other hand, at least some versions of GCC would emit -Werror=redundant-move in places where such a std::move would be added unconditionally, see c00948d9bd35dfb15a331c2163f32e9ee24644fd "Silence bogus -Werror=redundant-move (GCC 9)". */ #define HAVE_P1155R3 0 // Whether the OS provides a usable dynamic loading API #define HAVE_DLAPI 0 // Whether the OS uses the common UNIX dynamic loading API calls, like dlopen, dlsym, dladdr etc. // Use HAVE_DLAPI instead.
