MPFR 4.0.0-rc1 causes in-tree build of gcc to fail (error building mpc)
Using:
gcc-8-20171203
gmp 6.1.2
mpc 1.0.3
mpfr 4.0.0-rc1
isl 0.16.1
mpfr-3.1.6 works fine.

I've also sent additional info to mpfr at inria.fr, but that was
possibly rejected (sent to moderators), so this is just a heads up.
And yes I know its not an officially supported combination etc etc...
