But enough have to have sorted out many of the issues. For example, the gcc 4.3 series uses C99-style inlining and that has been implemented (conditionally on GCC capabilities), and various bits of R have been rewritten to work around mis-compiles by the gcc 4.3 branch. But note that gcc 4.3 is not released and not even branched with rather a lot of remaining regressions. I'd be wary of using high levels of optimization: last time I looked R failed to build correctly at -O3 on x86_64, and there were more problems with packages. Surely this is a topic that the posting guide directs to R-devel -- all the issues mentioned are programming ones, not R ones. -- Brian D.
