The function mpz_div_2exp was removed from MPIR 1.3 because it is a very old interface which was deprecated in GMP a long time ago when the new mpz_tdiv_q_2exp function was added, for example.
With MPIR 1.3 you have two options: 1) Replace all references to the deprecated function with the correct function name throughout your code. 2) Add some #defines to your gmp.h (or elsewhere in your includes), e.g. #define mpz_div2_exp mpz_tdiv_q_2exp. In the next version of MPIR we have inserted these #defines in the gmp.h file whenever MPIR is built with --enable-gmpcompat. Obviously the idea of deprecating functions is that people do (1) above, but after many years, this doesn't seem to have happened. People keep using the old functions. Bill.
