Snippet #663

Ok, found out what my linking problem was, and why I am running it to it for the first time when targeting 64-bit architecture (previously I had always just targeted 32-bit): GCC_SYMBOLS_PRIVATE_EXTERN actually hides Objective-C classes when building for 64-bit, unlike it does for 32-bit (Google informs that I am not the only one who was surprised by this). Solution? mv GCC_SYMBOLS_PRIVATE_EXTERN /dev/null (figuratively speaking).
