c-tree.h (C_TYPE_INCOMPLETE_VARS): New macro. 

	* c-tree.h (C_TYPE_INCOMPLETE_VARS): New macro.
	* c-decl.c (struct c_scope): Remove "incomplete" field.
	(pushdecl): Attach variables with incomplete types to
	the TYPE_MAIN_VARIANT of the incomplete type in question.
	(finish_struct): Look at C_TYPE_INCOMPLETE_VARS for variables
	to complete, not at current_scope->incomplete.  All such
	variables do need completion.
