[BusyBox] warning in cal.c

[Steven Scholz]

Hi there,

I do get the following warning

coreutils/cal.c: In function `build_row':
coreutils/cal.c:327: warning: value computed is not used

in build_row() line

                         if (julian) {
 >>>>>>>>>>>                     *++p;
                                 if (day >= 100) {
                                         *p = '0';
                                         p[-1] = (day / 100) + '0';
                                         day %= 100;
                                 }
                         }

So is it an error to write "*++p"?
Did the author ment to write something different?
Or is it realy just redundant?

At least at the first glance it works without this line!
