   5 # configuration options.  You can modify this shell script without
   6 # needing to rerun autoconf.

  13 #   target                The configuration target
  14 #   target_cpu            The configuration target CPU
  15 #   target_os             The configuration target OS
  16 #   target_optspace       --enable-target-optspace ("yes", "no", "")

  19 #   cpu_include_dir        CPU-specific include directory, relative to srcdir
  20 #   os_include_dir         OS-specific include directory, relative to srcdir
  21
