Cannot build on Mac using Xcode 4 and LLVM

[Rui Carmo]

As detailed in the mailing-list and the brew project (see below), QEMU currently either doesn't build with LLVM or builds and crashes upon runtime on Mac OS X Lion (or Snow Leopard if you've upgraded your compiler from gcc-4.2).

This seems to be tied to the internal representation of UINT16, but effectively means that you currently cannot run QEMU 1.0 or HEAD (for any target arch - I'm focusing on ARM and Intel) on a Mac.

QEMU now builds fine on MacOS, with LLVM-gcc and clang (we fixed both the typedef problems and the global-fixed-register variable).

Awesome, thanks.
