ert0067 Not enough characters in command '<option>' to guarantee
         uniqueness

     Explanation:  A sequence of characters which was accepted as an
     option in a past version of .RTLink is not long enough to guarantee that
     the correct option is selected.

     Action:  The minimum abbreviation for each linker option is
     documented in The CA-Clipper Linker--RTLINK.EXE chapter in the
     Programming and Utilities guide.
