Comment (by leif):
Obviously the `CC` from `gmp.h` gets overwritten with `$ac_cv_prog_CC`
(determined earlier), but I don't know the proper way to avoid that. (One
could of course "manually" unset it in the `MPC_GMP_CC_CFLAG` macro from
`mpc.m4`, or set it to the new value if appropriate, but that appears very
hackish to me. There must be some other way to update or invalidate
cached variables I think, but so far I haven't found one.)
The cause of the regression seems to simply be the use of newer autotools
(generating a `configure` script that now checks for the compiler
''before'' `MPC_GMP_CC_CFLAG` is called).
