Enabled RTREE is now the default for RSQLite and there is no plan to
change that. I will see if there is a more transparent way to enable
it, certainly having the SQLite flags be visible in Makevars.in would be
The configure setup for RSQLite is more complicated than I would like
because it supports building the included SQLite sources (default) but
