PR java/25366: ICE in do_resolve_class

[Andrew Haley]

This bug is fixed on 4.0 branch but not on mainline.  It was fixed on
the branch by this patch:

2005-10-01  Bryce McKinlay  <mckinlay@redhat.com>

	PR java/23891
	* parse.y (maybe_create_class_interface_decl): Set TYPE_PACKAGE for
	the newly created type. Set import lists here, not in create_class.
	(jdep_resolve_class): Set current_class.
	(do_resolve_class): Use current_class's TYPE_PACKAGE to determine 
	the current package context, not ctxp->package.
	(cicp_cache): Removed.
	(class_in_current_package): Simplify implementation using
	TYPE_PACKAGE.
	* jcf-parse.c (give_name_to_class): Set TYPE_PACKAGE.
	* java-tree.h (TYPE_PACKAGE): New macro.
	(struct lang_type): New member 'package'.
	* class.c (maybe_layout_super_class): Update current_class before
	calling do_resolve_class.

The patch to maybe_layout_super_class from 4.0 branch looks perfectly
reasonable and it fixes this problem on trunk and 4.1 branch.

Andrew.
