You make it so you HAVE to fix the warning by adding the option to make 
warnings into errors.

This does mean that you need to fix all the warnings that don't actually 
mean anything,

Good code shouldn't generate many warnings, either you have warnings 
enabled that you don't care about, or your code is doing things you have 
told the complier you shouldn't do.
