Silence spurious warning in lwcpp build GCC has a stupid-ass warning about snprintf() truncating its output if its return value isn't tested. But that's the bleeping point of snprintf() in the first place - that it will truncate its output. Why should I need to add completely pointless extra code to check a return value *that doesn't matter* in my specific use case just to shut up an overwrought warning. So disable the stupid-ass warning. Why, yes, I do have a strong opinion. Why do you ask?
