  Not so far. But to start with very easy improvements, any objections to
  deleting the #if USE_ZEROTAB things from gcdext_1.c ?

None whatsoever.

(We have a few such tables of varying sizes.  The top level
x86_64/gcd_11 and gcd_22 have one each, since count_*_zeros are slow for
older x86_64 CPUs.)

  BTW, looking at recent changes to that file, a ± character (plus/minus,
  unicode 0xb1, TeX \pm) was deleted in 46b4c2e7f148. Is it important to
  avoid non-ascii, and if so, what's the preferred way to write this
  symbol? "+/-" ?

Ask the perpetrator.  :-)
