  Attached is a patch to move the current (slow) gcd_2 to a separate file, rename
  it mpn_gcd_22, change argument and return type, and add a basic test.

Nice!

  Do you agree with the naming in 

  typedef struct
  {
    mp_limb_t d0, d1;
  } mp_double_limb_t;

  or should it be something else?

That's a good name.  (I doubt we will need structs for 3 and 4 limbs, so
we don't need a fancier naming scheme.)

  Next would be speed support, and then it's easier to try ways to make it
  faster.

Speed support would be very welcome!
