the readme file that accompanies sendmail notes that "You must
pre-load "cf.m4"...

>	is missing and OSTYPE should be set.

...and the clientproto.mc file says that "You MUST also define an
`OSTYPE'".  it also says:

#  This the prototype for a "null client" -- that is, a client that
#  does nothing except forward all mail to a mail hub.  IT IS NOT
#  USABLE AS IS!!!
