Does Clang also fail to compile this? Clang was updated from 1.6 to 2.0 with Xcode 4, worth a try.

Also, from your version listing it seems to be llvm-gcc (gcc frontend with llvm backend I think), is there no more straight gcc (with gcc frontend and backend)?

FWIW, on 10.6 the default gcc is a straight 4.2

    i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664)

There is an llvm-gcc 4.2 but it uses a slightly different revision of llvm
