Log message:
Work around a bug in SunOS complex.h to make this build with Suns gcc.

Log message:
Explicitly depend on gmp>=4.3.2 and mpfr>=2.4.2.

Log message:
allow to use gmp/mpfr/mpc which comes with the system (eg on
NetBSD-current with gcc45)

Log message:
Update to mpc-0.9
Prompted by Stathis Kamperis.

Changes:

  * 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
      + exp: close to infinite loop for argument close to 0
      + sqrt: close to infinite loop for argument close to 1
      + 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

Log message:
Import MPC (multiprecision complex arithmetic library) version 0.8.2
as math/mpcomplex.
Packaged by Marko Schuetz for pkgsrc-wip.

MPC is a C library for the arithmetic of complex numbers with
arbitrarily high precision and correct rounding of the result.
It is built upon and follows the same principles as MPFR.
