We need 'i' to index reg_list->reg in the body of the loop. That means we need to write this as #define for_each_present_blessed_reg(i) \ for_each_reg(i) \ if (find_reg(blessed_reg, blessed_n, reg_list->reg[i])) (Which, in hindsight, makes sense since we're replacing a for_each_reg() loop.) Thanks, drew
