cc1plus: warning: -Wabi won't warn about anything [-Wabi]
cc1plus: note: -Wabi warns about differences from the most up-to-date ABI, which is also used by default
cc1plus: note: use e.g. -Wabi=11 to warn about changes from GCC 7

https://github.com/gcc-mirror/gcc/commit/ae5baadd3e080a87f050bdfea2c50737c4a7f915 changed behaviour of '-Wabi -fabi-version=n'. Now gcc requires '-Wabi=n' instead and complains about '-Wabi' doing nothing.
Is this bug about fixing other packages or a request to change something in gcc itself?
Well, it's a bit odd that GCC should pass -Wabi in its own build system, so the bug is about sys-devel/gcc. Perhaps it's used for some architectures and not others?
I guess we can close this now.
