This short example program from "Using C++ by Rob McGregor will not
complile with djgpp and produces the messages below.  I assume it
probably does compile on some other compiler so I thought you could tell
me what's making djgpp puke.

//////////////////////////////////////////////////////
//  Module  : array2.cpp
//
//  Purpose : Shows the simple usage of a
//            one-dimensional array
//////////////////////////////////////////////////////

#include <iostream.h>

void main()
{
   // Create an array of five integers
   //
   float num[5];

   // Iterate through the array elements, initializing
   // them with float values
   //
   for (int i = 0; i < 5; i++)
      num[i] = i * 2.25f;

   // Iterate through the array elements,
   //   displaying their values...

   for (i = 0; i < 5; i++)
      cout << "num[" << i <<"] == " << num[i] << '\n';
}


Produces these messages :

testfile.cpp: In function `int main(...)':
testfile.cpp:25: name lookup of `i' changed for new ANSI `for' scoping
testfile.cpp:19:   using obsolete binding at `i'

Line 25 is:    for (i = 0; i < 5; i++)
Line 19 is:     for (int i = 0; i < 5; i++)
djgpp compiler does not seem to tell me if these are error messages or
warnings. Is there any way to tell ?

Also what are these messages trying to tell me ? I have no idea what
they mean. How can I make this program work ?

I searched for "binding" and "scope" in the faq but didn't find
anything.

Is there anywhere I can find a list of errors and warnings with
explainations of what they mean ?
