dnl Special processing of paths depending on whether --prefix,
dnl --sysconfdir or --localstatedir arguments were given. What's
dnl desired is some compatability with the way previous versions
dnl of BIND built; they defaulted to /usr/local for most parts of
dnl the installation, but named.boot/named.conf was in /etc
dnl and named.pid was in /var/run.
dnl
dnl So ... if none of --prefix, --sysconfdir or --localstatedir are
dnl specified, set things up that way. If --prefix is given, use
dnl it for sysconfdir and localstatedir the way configure normally
dnl would. To change the prefix for everything but leave named.conf
dnl in /etc or named.pid in /var/run, then do this the usual configure way:
dnl ./configure --prefix=/somewhere --sysconfdir=/etc
dnl ./configure --prefix=/somewhere --localstatedir=/var
dnl
dnl To put named.conf and named.pid in /usr/local with everything else,
dnl set the prefix explicitly to /usr/local even though that's the default:
dnl ./configure --prefix=/usr/local
