From: Dave Taht <d...@taht.net>
When compiled on arm and gcc 4.9.2, the compiler picks out two sets of
variables passed by reference that "might be used uninitialized".
They aren't, but certainly in the getnet case it was not immediately
obvious to either me or the compiler.
Quiet the warnings by explicitly initializing these variables.
