A second release candidate for GCC 4.3.1 is available from ftp://gcc.gnu.org/pub/gcc/snapshots/4.3.1-RC-20080529
and shortly its mirrors. It has been generated from SVN revision 136151. The branch is still frozen and all checkins until after the final release of GCC 4.3.1 require explicit RM approval. If all goes well this candidate will become the final 4.3.1 release early next week. Thanks, Richard.
