GCC 10 transition

[Norbert Preining <norbert@preining.info>]

Dear GCC Team,

(please Cc)

I would like to ask about how we should deal with gcc10 creating
completely different symbols than what we currently have.

Are we supposed to bump the ABI version for every library due to the
symbols changes, or is there any other procedure to be expected.

The announcement of Matthias:
> I'm planning to make gcc-10 the default after gcc-10 (10.2.0) is available
> (upstream targets mid July).  binutils will be updated before making the GCC
> switch. The GCC 10 switch involves some minor library transitions for D, gccgo,
> M2, which should be no-brainers. The gnat transition will be handled separately
> by the debian Ada maintainers.
Doesn't really hint at problems to be expected, but we see considerable
FTBFS due to symbols disappearing.

Do you have any guideline on how to deal with these cases?

Thanks

Norbert
