mpc.h, mpc.texi:

   defined and documented return value for functions computing two results
   It is obtained from the macro
      MPC_INEX12 (inex1, inex2)
   and decomposed again as
      MPC_INEX1 (inex) and MPC_INEX2 (inex)
sin_cos.c, sin.c, cos.c:
   First steps to moving the computation of sin and cos into sin_cos:
   If one of rop_cos or rop_sin in sin_cos is NULL, then it is not computed.
   So far, implemented for special, real and purely imaginary values.
