test: Silence gcc warnings
warning: cannot optimize possibly infinite loops
gcc does not detect that the "infinite" loops are actually just one or
two iterations, depending on the has_similar value being FALSE or
TRUE. It realizes it if the iteration variable and the iteration stop
value are both enum values.
