Indeed, on the SPARC we seem to have problems (miscompilations: fortran/45277, target/45363, c/45407) with any newer versions of GMP/MPFR/MPC. So I'm going to add a blurb to the platform-specific instructions about that. > Somehow, we need to keep an eye on these issues so that if a new > version of a library changes in a way that breaks the gcc build we > notice.
