PR c/83656 - missing -Wbuiltin-declaration-mismatch on declaration without prototype
gcc/c/ChangeLog:
PR c/83656
* c-decl.c (header_for_builtin_fn): Declare.
(diagnose_mismatched_decls): Diagnose declarations of built-in
functions without a prototype.
* c-typeck.c (maybe_warn_builtin_no_proto_arg): New function.
(convert_argument): Same.
(convert_arguments): Factor code out into convert_argument.
Detect mismatches between built-in formal arguments in calls
to built-in without prototype.
(build_conditional_expr): Same.
(type_or_builtin_type): New function.
(convert_for_assignment): Add argument. Conditionally issue
warnings instead of errors for mismatches.
