template function

["Dr. Michael Albert" <albert at esther dot rad dot tju dot edu>]

Dear Friend:

First let me say how much I appreciate Cygnus's work with the GNU
project and the effort of all of those involved.  

I'm afraid today, though, I'm here to issue a bug report (forgive
me if I am mistaken, but to the best of my knowledge this code
is ANSI).

Thank you.
 -Mike
