And I wonder what are the downsides of setting this option. The LLVM-GCC 4.2
Release Notes list six GCC 4.2 features that are not available in LLVM-GCC
4.2. The only one that I think might mean anything to me is OpenMP. Is there
any reason to think that I should be concerned about this in 2008 in Mac OS
X 10.5 Leopard? I don't explicitly use separate threads in any of my
applications, and they aren't all that processor-intensive.
