  o Code simplifications and refactoring:
    - During configure, detect when we're building with clang version 3.0 or
      lower and disable the -Wnormalized=id and -Woverride-init CFLAGS.
      clang doesn't support them yet.
Build with warnings and clang 3.0 --enable-gcc-warnings enables two warnings that clang doesn't support, so the build fails. We had hoped clang 3.0 would add those, but it didn't, so let's just always disable those warnings when building with clang. We can still fix it later once they add support 2011-12-12 15:36:08 +01:00			`o Code simplifications and refactoring:`
