There is now released gcc-5.1.  Upstream GCC has approved it now for trunk,
that is gcc-6.0.

(For Fedora a backport can be easily done for whatever version combinations.)

So you request forward/backward compatibilities, specifically:

(1) Do you request future gdb-7.10 is compatible with existing gcc-5.x?

(2) Do you request future gcc-6.0  is compatible with existing gdb-7.9?

With an answer for (1) and (2) we can decide on how to implement it.
