A cursory search would seem to indicate that there are multiple
different versions of the original file under apparently different
terms:

   http://www.google.com/codesearch?hl=en&lr=&q=file%3Aargproc%5C.c

Specifically the version distributed with ctags is already GPL'd.

Would it do to replace the version we have with one of the GPL'd ones
and then reapply the original changes?
