Epetra: Remove build warnings
Created by: ZUUL42
Epetra builds should not emit any warnings that will be promoted to errors once Werror is set in the GCC 7.2.0 automated build.
Currently Epetra has a number of warnings that need to be handled before we can set Werror for all packages. A recent test build was performed with -Werror set for Epetra. The CDash report can be found here.
Motivation, Context and Related Issues
Issue #3178 is working toward turning Warnings as Errors on for all packages.
