Cfront 2.0 will give an error message if you try to make a
declaration the (only) subject of an if or else clause.

It is far from clear what something like this should mean:

	if (x > 0)
		int y;

Clearly, this cannot conditionally declare y in the surrounding
context: how could one possibly compile this:

	if (x > 0)
		int y;
	y++;

If you really want the declaration to live in a block of its own,
you can still write

	if (x > 0)
		{ int y; }

and your meaning is then clear.
