I'm working with a C compiler which requires function prototypes, and have just
spent a day converting released X header files to include this information.

Sample original code:

    extern void XtStringConversionWarning();
        /* String   from;       */  /* String attempted to convert.     */
        /* String   toType;     */  /* Type attempted to convert it to. */


Converted into function prototypes:

    extern void XtStringConversionWarning(
    #ifdef NEED_PROTOTYPE
        String   from,        /* String attempted to convert.     */
        String   toType       /* Type attempted to convert it to. */
    #endif
    );

The converted code will still work with a compiler that doesn't understand
function prototypes, but defining NEED_PROTOTYPE will satisfy the compiler
that requires them.


Oh please, X people, could the X header files be modified along these lines in
the next release, to save lots of reconversions in the future?
