Does this work?

[terrycloth]

for (pnode == pnodeFirst; pnode; pnode = pnode->pnodeNext)
   {
   int i;

   if (pnode->k == kSource)
      i = pnode->l;
   else if (pnode->k == kDest)
      pnode->l = i;
   }

I know this variant works differently between the last two compilers I've used:

for (i=0; i<=2; i++)
   {
   int j=0;

   PrintNumber(j);
   j++;
   }

K+R is no help, they don't seem to address this issue at all.
