We have this:
‘-Wdeprecated-non-prototype (C and Objective-C only)’
Warn if a function declared with an empty parameter list ‘()’ is
called with one or more arguments, or if a function definition with
one or more parameters is encountered after such a declaration.
Both cases are errors in C23 and later dialects of C.
This warning is also enabled by ‘-Wc11-c23-compat’.
I don't think it's good use of developer time to change () to (void) where this
is possible, so I believe this warning is sufficient.
