do keep in mind that this kind of message is almost never an error.  
It's simply a warning that you wouldn't even see w/o -w. All that it  
means is that a scalar with an undefined value is being evaluated to  
a string (which results, by default, in an empty string).

Is the build failing or halting at this point for you?

That said, it's indeed a good to point those out, as someone either  
should have initialized a scalar when it wasn't, or that someone was  
expecting the scalar to always have a value, and so the absence of it  
may indicate an unexpected condition resulting from an error elsewhere.
