  Except that the function refmpz_powm seems to be non-existant...
  
That's the reason for the article, "a refmpz_powm".  :-)

  Anyway, I think it is unlikely that the real implementation of
  mpz_legendre will ever use mpz_powm, so I think mpz_powm should do here.
  
OK!

  I've pushed the new refmpz_legendre now.
  
Nice!
