   4 # ugly, and quite broken by design.
   5 #
   6 # The intention is to pass additional flags to gcc to further optimise
   7 # generated code. It _will_ make it impossible to debug, may fail to
   8 # compile some code, and even generate curdled binaries. It is completely
   9 # unsupported. Any questions should be directed to <abs@absd.org>.
