Summary: lint mods

For those with source code, here's an addition to "lint" to generate warnings
about
	float /= int
and
	int /= float
constructs.  This is an addition to the 4.1BSD version of "lint/lint.c",
in particular to the function "clocal"; your mileage will vary.
As always, the trade secret status of the code involved precludes a clearer
posting.  The addition is conditioned on "OLDVERSION".

	...
	NODE *
	clocal(p) NODE *p; {
	...
		switch( o = p->in.op ){
	#ifndef OLDVERSION
		case ASG MUL:
			if (pflag && p->in.right->in.op == SCONV)
				werror( "mixed-mode *= may surprise you");
			break;
		case ASG DIV:
			if (pflag && p->in.right->in.op == SCONV)
				werror( "mixed-mode /= may surprise you");
			break;
	#endif /* !OLDVERSION */
	...
