Yeah, I expected all hell to break loose - only to be pleasantly
surprised by this being the only issue I encountered. So I figured
fixing this might be worthwhile - even if this surely does not fix
-Werror builds on all platforms and/or compilers.
Alternatively - is there a way to use -Werror only for building the
actual sources, not the configure tests? I didn't find one, but my
autoconf-fu is pretty limited...
