#if 0
    Is the following legal ansi c?
    I beleave that it is, but if not, I would like to know why not.
    Note in particular that vprintf() is called twice in a row.
    I just discovered a vprintf() that changes arg_ptr when
    I do this, causing the second vprintf to fail.
    In case you are wondering, the bad vprintf() came from Watcom.

void report( char *fmt, ...)
{
    va_list arg_ptr;
    
    va_start( arg_ptr, fmt);
    vprintf( fmt, arg_ptr);
    vprintf( fmt, arg_ptr);  /* Yes, we want to print it twice.     */
                             /* In the original program, the second */
                             /* was vfprintf to a log file.         */
    va_end( arg_ptr);
}

main( int argc, char **argv)
{
    int a;
    
    for( a=0; a<argc; a++) {
        report( "arg %d is %s\n", a, argv[a]);
    }
    return 0;
}
