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

 861 #   a copy of ${toolprefix}make (this should work for everybody who
 862 #   doesn't override TOOLDIR via /etc/mk.conf);

 864 #   in the PATH (this might accidentally find a non-NetBSD version of
 865 #   make, which will lead to failure in the next step);
