How do you wish to parse:

	myfunction (a, b, c) {
		var z
		z = 1 + 2
	}

You can parse "z = 1 + 2" multiple ways:
	(z = 1) + 2
or
	z = (1 + 2)

The default behavior of SmaCC picks the shift action over the reduce
action, so the second choice is the one that it picks.

To fix this problem you can
A) ignore it, if you want the second choice
B) change your grammar to remove the ambiguity
C) add a precedence rule to tell SmaCC the priority of the +, -, and =
tokens
The SmaCC tutorial has an example of both B & C.
