I had a go at compiling on my Macbook, which runs Apple's most recent
cat. I had to fix a couple of issues, which I think are down to new
stuff in the system headers:
 * the os/object.h header will try to use Objective-C syntax unless
   explicitly squashed
 * some of the headers we use in the cocoa ui frontend use the
   'Blocks' Apple extension, so won't build except with clang or
   the (now rapidly aging) Apple gcc, so to do a build with a
   modern gcc we need to support specifying the Objective-C compiler
   separately.

Peter Maydell (2):
  configure: Define OS_OBJECT_USE_OBJC=0 for MacOSX builds
  Support using a different compiler for Objective-C files
