As everyone has probably gathered from the first sentence of most of the other posts, GSoC 2011 is now over. I accomplished some of the goals I had for the last quarter, but was unable to get GCC2 support to work. The compiler is different enough to not work with the same options, and even after adding a GCC2 tool definition to kBuild I found that it was too old to compile some of the VirtualBox code. Various workarounds I tried for this proved unhelpful, so the additions will currently only compile and run on a GCC4 or GCC4 hybrid Haiku.
