[PATCH] only have varray name with ENABLE_CHECKING

[Steven Bosscher]

We always have a name field for each varray, but it's only used with checking 
enabled.  This patch makes the field disappear with checking disabled.  OK?

Gr.
Steven

	* varray.h (struct varray_head_tag): Remove name field if checking
	is disabled.
	* varray.c (varray_init): Only set the name field when checking is
	enabled.  Mark the name argument unused if checking is not enabled.
