Welcome to the differences between UN*X versions.  V7, and the BSD
derivatives (yes, wizards, I know BSD is really V32 :-) don't have any
way to specify a null suffix.  Sys3 and SysV have some added
functionality to allow for null suffixes.  (I don't remember the
syntax at the moment, and I'm on an Ultrix machine, oh well.)  It's
not just a matter of changing .SUFFIXES...  make(1) has to know about
how to do it.

UNIX... the only operating system where reinventing the wheel is a way
of life.  (But at least most of the wheels have shiny chrome :-).
