We need to think about the default user (which will likely not unpack gmp, mpfr and mpc) into the gcc source tree. We would need input from Gerald (assuming he still supports the official FreeBSD ports builds of gcc). Blinding accepting a patch to remove this block of configuration will likely break this downstream; even if it otherwise makes logical sense to do so. Regards, Loren
