Useless assignment here and everywhere.

Initializing returncodes to errorstate is a cheap way to prevent
accidentally returning (uninitalized) success returncodes which
can lead to catastrophic misbehaviour.

That is old thinking. Current compilers do live/dead analysis
and tell you about this at compile time which is better than relying
on default behavior at runtime.
