Thanks.  Unfortunately, this patch is too large for us to be able to
accept it without your assigning to the FSF the copyright for your
changes.  Would you be willing to sign the legal form for that?  If
so, I will send you the form, and we could then install your changes
when the legal paperwork is done.
