 If compilation succeeds then you are not affected. The definitive
 indicator that it's working correctly is that the verbose output shows
 `/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1`
 in the include search paths rather than
 `/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1`.
