 0.8.0+.
 Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
 their locations.  Source code for these libraries can be found at
 their respective hosting sites as well as at
 https://gcc.gnu.org/pub/gcc/infrastructure/.  See also
 http://gcc.gnu.org/install/prerequisites.html for additional info.  If
 you obtained GMP, MPFR and/or MPC from a vendor distribution package,
 make sure that you have installed both the libraries and the header
 files.  They may be located in separate packages.
