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...
