GCC 6.3 Release Candidate available from gcc.gnu.org

[Jakub Jelinek]

The first release candidate for the third release from the
GCC 6 branch, GCC 6.3.0, from SVN revision r243646, is available from

  ftp://gcc.gnu.org/pub/gcc/snapshots/6.3.0-RC-20161214/

and shortly its mirrors.

I have so far bootstrapped and tested the release candidate on
x86_64-unknown-linux-gnu.  Please test it and report any issues
to bugzilla.

If all goes well, we'd like to release GCC 6.3.0 in the middle of the
next week.
