Thanks for the reply Brian and Bill Hart also. I have changed my mind and
decided to claim MPIR compatibility instead of GMP compatibility for my
Eiffel interface. Now I have a question about another function -
mpz_probable_prime_p. It seems odd to me that this functions has a
gmp_randstate_t argument. Could I ask what the purpose of this argument is?

Chris Saunders

I was reading the documentation on mpz_probab_prime_p. At the bottom of
the
documentation of this function it says "This function is obsolete. It

documentation for this function. Does this mean that in the future I can
expect GMP and MPIR to be incompatable? Might I suggest that this would
be
unfortunate.
Although our general intention is to remain as compatible as possible,
GMP and MPIR will never be completely exchangeable as their are always
going to be a few functions that will exist in one but not in the
other.
For example, we will never implement the so called 'secure' functions
such as mpn_powm_sec() since we don't consider it sensible to use
either GMP or MPIR where security matters as the code is completely
inappropriate for such uses.
In the area of trial division and (probable) prime testing, there is
currently some divergence that needs careful consideration. We have
not planned a way ahead on this right now but we do see the
maintenance of a high level of GMP/MPIR compatibility as important
where the path taken by GMP makes sense.
