--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. I think the C language doesn't specify this since zero-sized arrays
are a GNU extension and thus in C no zero-sized types/decls exist?
So not sure if there's anything to fix - Joseph?
Note that for global unique addresses you can use global objects of size 1,
like a char object. Not sure why you think using a GNU extension is
superior?
