Hi Andreas,

I don't understand what you suggest.  

Imagine the following configure lines:
- configure --prefix=/usr -> sysconfdir will be /etc
- configure --sysconfdir=/etc -> no prefix, sysconfdir should be /etc
  but is indeed currently /usr/local/etc
- configure --prefix=/test --sysconfdir=/etc -> sysconfdir gets set to
  /test/etc
