      are over- or underflows during the computation

  - Speed-ups:
    - mpc_pow_si through binary exponentiation

      arguments
    - mpc_exp: close to infinite loop for argument close to 0
    - mpc_sqrt: close to infinite loop for argument close to 1
    - mpc_add_si: replaced macro by function, since the macro evaluated the
      same expression twice
  - Logging feature for debugging:
      ./configure --enable-logging
      #include "mpc-log.h" instead of #include "mpc.h"
  - Minimally required library versions: gmp 4.3.2, mpfr 2.4.2
