Zoltan: Remove Build Warnings
Created by: ZUUL42
Issue #3178 is working toward turning Warnings as Errors on for all packages in order in ensure Trilinos maintains a high level of SQA practices across the project. Currently Zoltan has a warning that need to be handled before we can set Werror for Zoltan and eventually all packages.
A recent test build was performed with -Werror set. The CDash report can be found here.
Once the Zoltan build doesn't emit any warnings that will be promoted to errors, we can set
-Werror in the GCC 7.2.0 automated build.
