A first release candidate for GCC 4.3.1 is available from ftp://gcc.gnu.org/pub/gcc/snapshots/4.3.1-RC-20080523
and shortly its mirrors. It has been generated from SVN revision 135793. I have sofar bootstrapped and tested the release candidate on x86_64-unknown-linux-gnu. The branch is still frozen and all checkins until after the final release of GCC 4.3.1 require explicit RM approval. Thanks, Richard.
