  Dear Mr. Westley,

  Although not Ada specific,  you might want to look at the
  comparison utilities on my web page,  these are available for OS/2, NT,
  and DOS.   http://world.std.com/~jdveale

  These tools perform a true word-by-word comparison where words may be
  separated not only by blanks,  but by common programming language
  delimiters.  As a result it can be insensitive to many formatting
  changes.  It can also be configured to ignore most Ada comments,
  and changes in text flow.

  You might also find the interactive "bounce merge" facility useful.
  This allows you to 'bounce' lines from one file to another and save
  the results.
