--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  My preference would be to resolve pr82922 and diagnose all calls to
functions without a prototype.  Short of that, this could be handled by saving
the type of the first call to a function without a prototype in a translation
unit, comparing it to the type of each subsequent call, and warning if they
don't match.
