GCC 4.9.3 Status Report (2015-06-17) - branch frozen for release

[Jakub Jelinek]

The GCC 4.9 branch is now frozen for preparing of a release candidate for
GCC 4.9.3.  All changes to the branch require release manager approval
from now on until 4.9.3 is released.

I'll announce the GCC 4.9.3 release candidate once it is ready.
