$ /usr/bin/gcc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
That's llvm-gcc-4.2. Known not to work for Wine.
At http://wiki.winehq.org/MacOSX/Building#head-f6eb9d865f21b525ac313d62cbb73ca36e07a0a3 it's recommended that you install Apple's gcc-4.2 and specify the use of that when configuring. Give that a try.
