clang-3.2 and earlier on Mavericks

[Ryan Schmidt]

Why are clang-3.2 and earlier not supported on Mavericks? This is inconvenient. It was very convenient to be able to install all versions of clang from 2.9 thru current on Mountain Lion, so that when bugs were reported on older Xcode versions I could simulate their environment without needing to change mine by changing configure.compiler to an earlier clang. Now to test for this I have to leave my primary machine and boot up another machine or VM with an earlier OS X version.
