[Anthony G. Basile]

Hi everyone,

Kensington suggested updating the news item on the new c++11 abi for
gcc.  Since this news item now appears for all new installations of gcc
it can be annoying.  I'm proposing to change it as below, but I have one
concern.  It is important for anyone upgrading from gcc-4 to gcc-5.  But
if an upgrade to gcc-5 removes gcc-4, then the message won't show up
while it is still relevant.

Any suggestions on how to proceed?

Nit: You probably want <sys-devel/gcc-5, not <=sys-devel/gcc-5.

Portage will flag the news item as relevant as soon as it sees gcc-4*
installed. If a future depclean removes that version, I believe
portage will still display the news item. Even if it doesn't, the user
would still have had to ignore the news item and run the depclean
first.

fwiw, I think although the root causes are similar, the differences
between the major GCC versions probably warrant their own separate news
items, unless there is updated information relevant to first-time
viewers. 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.

HTH,
Michael/veremit.
