What's the idea behind having a COPYING.txt file on Windows instead
of a COPYING file?

e.g. ui/gtk/about_dlg.c:

#if defined(_WIN32)
  absolute_path = get_datafile_path("COPYING.txt");
#else
  absolute_path = get_datafile_path("COPYING");
#endif

If there is a good reason, how about renaming your COPYING to COPYING.txt
(and perhaps create a dummy COPYING in case autotools complain)?

Thanks
   Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
