I think that this is the case; I think it's up to the GCC devs to decide whether
this is a problem for them or not -- I've added my 2cents to the GCC PR and I'm
still hoping for the guys to fix it, even though it is outstanding for quite
some time now.

I'll try to make this explicit in the Debian changelog.

Best,
Michael
