I'd probably constrain the existing news items closer to ~sys-devel/gcc-5 perhaps - or >= gcc-4.7 <gcc-6 or some-such - at the appropriate discretion, to avoid the immediate problem you assert.
I'm not sure news has the facility to re-mark-unread existing 'read' "old" news items, and thus re-display to users who've already seen the original. As a conservative user still using gcc-4.9 (for now, but ready to take the plunge on gcc-5 [Yes, really!]) I would welcome a TL;DR on the things to watch out for when building apps with the new major versions of GCC going forward.
