invalid compiler warning error

[Guest Joe]

    char x = 8;
   for(x; x < 100; x++)
   {
       nop();
   }

Produces the warning:

"Warning in line: No code generated for this expression"

 

This is incorrect, the code is valid and should be produced.

 

The code below is functionally the same, and it does compile...

    char x = 8;
   for(x=x; x < 100; x++)
   {
       nop();
   }

 

The only difference is:

   x=x

in the for loop.

    for(x; x < 100; x++)

 

Try

   for(; x < 100; x++ )
