These have now been removed.
Trac ticket 295 , I removed the old gcd stuff and associated functions , and
there is one further point mentioned
"Also, the function mpn_ngcd (in ngcd.h) seems to be a duplicate of mpn_gcd. I
think we can probably get rid of it. "
here is the diff between the two

So it look like gcd and ngcd are the same but with gcd has been updated to the
latest thresholds , I think?
