I have trouble with linked lists in DJGPP. This is a piece of code
I found  "C++ for dummies" and it worked in Turbo C++, but in DJGPP
I get:
1. warning: name lookup of `pC' changed for new ANSI `for' scoping
2. warning:   using obsolete binding at `pC'
What's wrong?

(member variables)
static Card *pFirst;
Card *pNext;

(in constructor)
if(pFirst == 0)
{
	pFirst = this;
}
else
}
2.	for(Card *pC = pFirst; pC->pNext; pC = pC->pNext)
	{
	}
1.	pC->pNext = this;
	}
}

In this destuctor, however, no error is generated. Why?

Card::~Card()
{
 if(pFirst == this)
 {
  pFirst = pNext;
 }
 else
 {
  for(Card *pC = pFirst; pC; pC = pC->pNext)
  {
   if(pC->pNext == this)
   {
    pC->pNext = pNext;
    break;
   }
  }
 }
}
