435.1.1 by Matthew Fuller Pull the static code out of gram.y and into a seaprate parse_yacc.c.	1	/*
	2	* Parser routines called from yacc code (gram.y)
435.1.2 by Matthew Fuller Leave some comments on these files to point at their minor redundancy	3	*
	4	* This is very similar to the meaning of parse_be.c; the two may be
	5	* merged at some point.
