Because you shouldn't be using gcc on a modern (post full 64-bit transition) OS X system. The llvm/clang/dtrace toolset is far superior.
Honestly, the gcc tools were never that great. On Sun systems, the Sun Studio set was always far superior and the other vendors had their own equivalents. Linux has just been "stuck" with gcc and the related Gnu tools since no one ever made anything better.
