The following program gives a warning I wasn't expecting.  (This is
reduced from gnu tar.)  I don't know what ansi says about it -- I
only have K&R2 as a reference.
    struct one {
	char buf[10];
    };

    struct one *f();

    char *
    g()
    {
	return f()->buf;
    }

The warning follows (from "gcc -c x.c"):
    x.c: In function g:
    x.c:10: warning: return of non-volatile * pointer from volatile *
