* gcse.c (expr_hash_table_size): Now unsigned.
	(compute_ae_gen): Local variable `i' now unsigned.
	(compute_ae_kill, pre_insert_copies, pre_delete, pre_gcse): Likewise.
	(compute_transout, hoist_code): Likewise.
	(compute_local_properties): Likewise, also hash_table_size.
	(alloc_expr_hash_table): N_INSNS now unsigned.
	(delete_null_pointer_checks): Mark arg F as unused.
