This is not required, (and likely undesirable). Use the " __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__" macro - which is provided by GCC and clang for all versions that produce OSX code (I would imagine that any compiler would need to implement it - since the system headers depend on it heavily). thus: #if defined (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__) \ && (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ >= 1070) \ /* && (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ < fixed-version) */ ... code for buggy Lion ... #else ... the rest #endif
