First, to add to the parent comment, you can install later versions of GCC on the x86 gcc2 builds as well. There is also a port of LLVM. Second, not directly related to what changed with the ABI, but it I think it would be more hassle than it is worth to try and make newer versions of GCC emit compatible binaries. There is work to run Haiku GCC 2.95 libraries alongside binaries built with a newer version. The runtime loader would be responsible for picking the correct so files. This also would work on the x64 builds as well, similar to how Linux (and others) can load x86 programs on x64 OS's. This feature is close to working but there were some last minute issues found, so it was left out of the Beta.
