  36 # you should not need to take any special action.  Otherwise, you
  37 # should set the environment variable HOST_SH to a POSIX-compliant
  38 # shell, and invoke build.sh with that shell.  (Depending on your
  39 # system, one of /bin/ksh, /usr/local/bin/bash, or /usr/xpg4/bin/sh
  40 # might be a suitable shell.)
