GMP in COPYING.Ylonen

[Jeff Bailey]

COPYING.Ylonen contains:
[ GMP is now external. No more GNU licence. ]

I don't see how GMP is linked in at all.  rms asked me to look into this, 
because this might constitute a license conflict.

Thanks for your help!

not a fault of the bell makes the sound poor.
