   9 # to csh, so put this in to make it use the Bourne shell. In systems where
  10 # /bin/sh is not a Bourne-compatible shell, this line will have to be edited,
  11 # or "make" must be called with a different SHELL= setting.

  16 # If a build name has not been specified by running this make file via a

  18 # operating system and the machine architecture and use that. This does not
  19 # provide an override for the OS type and architecture type; they still have
  20 # to be used for the OS-specific files. To override them, you can set the
  21 # shell variables OSTYPE and ARCHTYPE when running make.
