  - #14669: Fixed extraction of CC from gmp.h

  - Fixed case of intermediate zero real or imaginary part in mpc_fma,

    found by hydra with GMP_CHECK_RANDOMIZE=1346362345

Changes in version 1.0:

  - First release as a GNU package

  - License change: LGPLv3+ for code, GFDLv1.3+ (with no invariant sections)

    for documentation

  - 100% of all lines are covered by tests

  - Functions renamed:

    mpc_mul_2exp to mpc_mul_2ui, mpc_div_2exp to mpc_div_2ui

  - 0^0, which returned (NaN,NaN) previously, now returns (1,+0)

  - Removed compatibility with K&R compilers, untestable due to lack of

    such compilers

  - New functions: mpc_log10, mpc_mul_2si, mpc_div_2si

  - Speed-ups:

    - mpc_fma

  - Bug fixes:

    - mpc_div and mpc_norm now return a value indicating the effective

      rounding direction, as the other functions

    - mpc_mul, mpc_sqr and mpc_norm now return correct results even if there

      are over- or underflows during the computation

    - mpc_asin, mpc_proj, mpc_sqr: Wrong result when input variable has

      infinite part and equals output variable is corrected

    - mpc_fr_sub: Wrong return value for imaginary part is corrected

Changes in version 0.9:

  - New functions:

    - mpc_set_dc, mpc_set_ldc, mpc_get_dc, mpc_get_ldc for converting

      between mpc type variables and C variables of type double _Complex

      or long double _Complex

    - mpc_sin_cos, computing simultaneously the sine and cosine

  - Speed-ups:

    - mpc_pow_si through binary exponentiation

    - mpc_pow_z when the exponent fits in a long

    - mpc_tan through the use of mpc_sin_cos

  - Bug fixes:

    - trigonometric functions: infinite loop due to overflow for large

      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

  - Speed-up of mpc_pow_ui through binary exponentiation

Changes in version 0.8.1:

      imaginary parts

  - Get default $CC and $CFLAGS from gmp.h (__GMP_CC / __GMP_CFLAGS,

    which are available as of GMP 4.2.3)
