   4 # to set things up for compilation. It's vaguely like a stripped-down
   5 # version of autoconf. It's intended to be run as part of make.sh. The
   6 # only time you'd want to run it by itself is if you're trying to
   7 # cross-compile the system or if you're doing some kind of
   8 # troubleshooting.
