Well, let me Quote a little from ANSI C X3J11 Section 4.1.5 "... The macros are
NULL, which expands to an implementation defined null pointer constant..."
^^^^^^^^^^^^^^^^^^^^^
What does this mean? It means null isn't defined as
#define NULL 0 or
#define NULL 0L but rather something like
#define NULL ((void*)0)

This is exactly it, you basically have one of two choices to eliminate the
error messages.
1.(easiest) Reduce the warning level to level 2 or level 1
2.(hardest) Apply the necessary cast to the assignment
int i;
char c;
i=65;
c = (char)i;
