This part has a real consequence - the previous patch does not apply for build
trees out of the src tree.  It may be even a makeinfo bug.

The change below is not needed for texi2dvi.  In fact it even breaks it.

As Fedora does not package texi2roff I did not test it.

Another possibility is to error out if $(srcdir)/GDBvn.texi exists so that no
disambiguities may exist.  GDBvn.texi would have to be removed from the
distributed tars.

Comment on this part is more than welcome.

This is a regression.


Thanks,
Jan
