If you are trying to forward-port your own, proprietary features into
a newer release of GCC for your own, internal use, that's your
responsibility.

If you wish to contribute new features to FSF GCC, they only will be
accepted into trunk. You would need to integrate the feature into
trunk and propose patches relative to trunk during Stage 1
development.  New features are not back-ported to FSF GCC release
branches.

Thanks David
