Yes. The simple rule is "if a poisoned identifier appears in the source
file (after escaped-newline removal, but before macro expansion) after
being poisoned, it is warned about. The only exception is if it appears
in the RHS of another #pragma poison directive, in which case it is
silently ignored."
