I tried to find out what you're talking about and all I could find was:

  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36750

I'm guessing we are already inhibiting that warning because grepping for
{0} shows a bunch of uses of this pattern both in toolstack and the
hypervisor. If this breaks something it's already broken.

Either way, sure. Let me re-generate the diff. I have strong philosophical
objections to keeping support for >10yo toolchains in detriment of >20yo
standards, but I'll just save the rant for another day.

Cheers,
Alejandro
