--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  Looks like I added the -Wno- option aliases for
-Walloc-size-larger-than= and -Walloca-larger-than= but missed the others.

GCC will only warn for unknown options if it emits other warnings so
-Wno-stack-usage alone won't cause a warning unless something else leads to
some other warning.
