Oops, sorry, I was thinking of the x86_64-pc-solaris* case, which wasn't supported prior to GCC 4.7 (PR 39150) That doesn't change the fact that this PR is clearly this FAQ http://gcc.gnu.org/wiki/FAQ#configure_suffix and will almost certainly be solved by using the contrib/download_prerequisites script as suggested at http://gcc.gnu.org/wiki/InstallingGCC
