 Flag USE_CPPHS
   Description: Non-manual flag to allow the build system to try cpphs first, and if that fails, then to try system-wide cpp (typically GNU). I've actually toggled the default, so the build system will try for a system-wide cpp first, and failing that, will try to use cpphs, installing it if necessary. I prefer cpp. I am not getting my most invaluable -Wundef option with cpphs using -optP-Wundef -optP--cpp in my ghc-options. Does cpphs implement it? Not sure...
