- Support staging
- Add LICENSE (GPLv2)
- Add USES=gettext

 - Switched to automake 1.11.6, see CVE-2012-3386.
 - #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.

This is on top of the following changes from version 1.0

 - Licence change towards LGPLv3+ for the code and GFDLv1.3+ (with no
   invariant sections) for the documentation.
 - 100% of all lines are covered by tests
 - Renamed functions
   . 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, which was 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.

Convert to the new LIB_DEPENDS standard and remove hard-coded
.so versions from a couple of dependent ports.

Bump PORTREVISIONS of all dependent ports.
