* Added support for compiling Haiku with GCC 4. The main difference is that

we use the libstdc++ (including it's headers) that comes with the
  compiler.
* Apparently option "-I-" has been deprecated, which is why we now treat the
  include stuff a bit differently.
* Removed avcodec from the Haiku image, since the library wouldn't build with
  gcc 4, and I'm not in the mood to fix that (declaration of an array of an
  incomplete type).
