%description
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.

The library is available as 32-bit and 64-bit.

%description devel
Header files and other files required for developing programs using MPC.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".
