[Bug c/94337] Incorrect "dereferencing type-punned pointer will break strict-aliasing rules" warning

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94337 --- Comment #2 from Vincent Lefèvre --- Why not having a level with no false positives? This would avoid to disable the warning globally. IMHO, using it when a union is involved is likely to generate false positives.
