[9fans] Unexpected 8c warning message

[Adriano Verardo]

Hi, all.

SDes_t  *SDList[2], *SD;
....
n = ...       //  0, 1, 2, ...
//SD = SDList[0];         <= uncommenting this one the warning disappear.

for (i = 0;  i < 2;  i++)
{
      SD = SDList[i];
      while (n && SD)
      {
            SD = SD->next;
            if (SD) n--;
      }
}

if (!SD) {  ..... }    ---> used and not set SD ???

8c shouldn't issue the warning message, beeing SD assigned in a loop
defined by constants ... unless there is a subtle (my) error that I 
don't see.

Thanks for the help.
