Re: [PATCH]: Use mpc_pow in the fortran frontend

OK. Thanks for checking for all the special cases to make sure MPC does
the right thing - and thanks for this patch.


PS: For those not following the MPC development, missing (C99/F2008)
functions are mpc_acos, mpc_asin, mpc_atan, mpc_acosh, mpc_asinh,
mpc_atanh. And MPFR misses (F2008) SCALED_ERFC. The implementation of
all of those is planned; the inverse complex trigonometric/hyperbolic
function will (hopefully) happen in the next few months.
