The C language does not require prototypes when the function definition
precedes the first use of it.  Prototypes are only required as forward
or extern declarations.  I have never heard of a compiler that required
prototypes in other situations, so adding them does nothing to enhance

If you turn up the warning levels to for whatever reason, that does not
make all warnings generated related to that reason.  Specifically, warnings
about missing prototypes never have anything to do with machine word size.
