Thank you, Mark. Let me know how it went. In the meantime I'll prepare the
change for gcc5 itself.

I am not worried about that since that should not cause any binary
incompatibilities (ABI). The problem we encountered was about source code and
API in a wide sense of that term.

I am not aware of it, and while originally I was thinking to request an -exp
run (after the GCC version update which is dragging due to broken ports), time
is not on our side and the change should be low risk.

Not with my current level of connectivity and my notebook a dead brick on top
of that. And my preference is to still build, but stow away (unless explicitly
requested to keep).

Yes, agreed. Version 5 is most important since it's the default; then 6; 4.x is
for retro computing fans ;-), so 7 will then be next.
