I second this.

touching the owl*.db files (or source files in general)
is not a good idea in my opinion. I prefer removing the patterns/owl*.c
files.

Both removing and touching is a bit crude as a matter
of taste. Since the touch in Tanguy is unconditional,
every time configure is run owl*pat.c files are rebuild.
This does have the advantage that you are guaranteed to build
the version you intended to have.

However for the moment I have no better idea. A new make rule
perhaps? make rebuildowl, that removes the owl*.c files.
This has the disadvantage that you might forget to run this rule.

One idea I have been thinking about would be to include both
standard *and* dfa compiled owl patterns
in the executable (which is already sizeable). Then you
can choose at runtime which pattern matcher you want to have.

Perhaps someone else has a better idea.
