Thw thing about Apple is they give no fucks about backwards compatibility for developers anyway. You&#x27;re a developer and you&#x27;re working with Apple tech, so naturally you were waiting in line in the cold to get their latest hw and sw, weren&#x27;t you?<p>This bit me on the ass when Apple forced a libstdc++ update on OS X 10.3 with a new ABI, permanently breaking all C++ compilation on my Mac. Compiling C++ programs for 10.3 was still possible, but you needed a 10.4 machine, the latest Xcode, and compatibility libraries to do it.
