I'd agree if the system header approach was cross-platform or if this was a BSD-only program or if we were aiming for complete compiler-implementation independence, but since we rely on GCC/clang all over the place already it seems nicer to avoid all the machinery for identifying which of the multiple different system header implementations is present, and instead just have a single implementation that works on all the hosts we care about... thanks -- PMM
