	gcc            : ChangeLog ChangeLog.tree-ssa c-simplify.c 
	                 calls.c expr.c stmt.c tree-cfg.c tree.h 

Log message:
	* c-simplify.c (gimplify_c_loop): Don't return a LOOP_EXPR for
	a do ... while (0) loop.
	
	* expr.c (expand_expr, case COND_EXPR): Be smarter about expanding
	a COND_EXPR with only one useful arm, which happens to be a GOTO_EXPR.
	
	* tree-cfg.c (remove_useless_stmts_and_vars): Don't remove user
	variables unless we're at -O2 or higher.
	
	* stmt.c (any_pending_cleanups): Lose argument THIS_CONTOUR, it
	was always passed in the value '1'.  Simplify body appropriately.
	* tree.h (any_pending_cleanups): Corresponding changes.
	* calls.c: (expand_call): Corresponding changes.
