From the SunOS manpage MACHID(1):

 "The following commands will return a true value (exit code of 0) if
you are on a processor that the command name indicates.

  sun, iapx286, i386, m68k, pdp11, sparc, u3b, u3b2, u3b5, u3b15, vax

 The commands that do not apply will return a false (non-zero) value.
These commands are often used within make(1) makefiles and shell
procedures to increase portability.

SEE ALSO
  arch(1), mach(1), make(1), sh(1), test(1V), true(1)"


  The list of processors implies that this is not a Sun-ism, but comes
with standard BSD 4.x.  What have I been missing from this discussion???
