 Synopsis: Problem creating static arrays

 State-Changed-Why:
     I couldn't reproduce the bug. However, something in the 
     generated assembly isn't quite right:
     	...
     	movw	_1x.SIZE_VALUE, %si
     	subl	$8, %esp
     	subl	$2, %esp
     	pushw	%si
     	pushl	$8
     	call	_Jv_NewArray
     	...
     
     I'm worried of the effect of a pushw on _Jv_NewArray which
     expects two integers. With the attached patch, the generated
     code becomes:
     	...
     	movswl	_1x.SIZE_VALUE,%esi
     	subl	$8, %esp
     	pushl	%esi
     	pushl	$8
     	call _Jv_NewArray
     	...
     
     Which sounds much better. Let me know how the patch works
     for you.
