IIRC, C89 compilers accept prototypes but not // comments.  In any
case, XEmacs has required prototype support for a decade but some
compilers that can compile XEmacs blow up on // comments.  I'm not
even sure when/if GCC started accepting them by default.

I think you need to require C99 (or possibly GNU extensions) to get //
comments.
