Just to add to what was said. The -m64 is *required* on OSX 64. If you don't include it, everything blows up. In fact you will get piles and piles of errors which all look very subtle and you will pull your hair out for months trying to figure out what is going wrong. All obvious to Michael, but I've been bitten by this and wasted hours of my life trying to figure out what had gone wrong.
In particular you'll find piles and piles of unresolved symbols. It will complain you have compiled for the wrong architecture and the symbols will all have extra leading underscores. VERY frustrating. Bill.
