Thank you, this worked like a charm.  I also had to add all possible
format source files to EXTRA_DIST so they would be included in the
distribution.  :)

I've included my current Makefile.am below for reference, in case anyone
is curious.  It works fine with the latest automake 1.7.2.

Thanks again for your help!
