I don't see any reason that this is true.  You just need to know about
the promotion rules.

If you mix prototypes and old-style definitions, you can get code
which compiles on both old and new C compilers (assuming you use some
sort of conditional compilation to turn the prototypes into old-style
declarations).  You still get most of the advantages of prototypes.
