Release of GNU MPC 1.2.0

[Andreas Enge]

We are very pleased to announce the release of version 1.2.0
"Hyacinthus orientalis" of GNU MPC, a C library for the arithmetic
of complex numbers with arbitrarily high precision and correct rounding
of the result, available from
https://ftp.gnu.org/pub/gnu/mpc/

The release features the new functions mpc_sum and mpc_dot and several
bug fixes, in particular to make functions more robust if the user reduces
the exponent range. It also contains the tool mpcheck for easier comparison
with computations by the C library on standard precision floating-point
numbers.

The library requires the presence of the recently released version 4.1.0
of GNU MPFR, and it is recommended to compile both with the most recent
version 6.2.0 of GMP.

We thank Jeffrey Walton, Dennis Clarke, Dagobert Michelsen and
Rob "sisyphus" for extensive testing of the release candidate.

Enjoy,

Paul Zimmermann and Andreas Enge
