Building ATF on OpenBSD box (2)

["Sven Dehmlow" <sven%kaffeechaoten.de@localhost>]

Hey,

As said in my previous eMail: OpenBSD's default is to handle compiler
warnings as errors.

This c++ "error" seems to be a simple compiler warning, too. However I'm
not that deep in c++ to fix it on my own.

Any hints?
