The first release candidate for GCC 4.4.3 is available from ftp://gcc.gnu.org/pub/gcc/snapshots/4.4.3-RC-20100116
and shortly its mirrors. It has been generated from SVN revision 155960. I have so far bootstrapped and tested the release candidate on x86_64-linux and i686-linux. Please test it and report any issues to bugzilla. The branch is now frozen and all checkins until after the final release of GCC 4.4.3 require explicit RM approval. If all goes well, I'd like to release 4.4.3 next week.
