Comment (by awulkiew):

 That's because `distance()` for Point-Linestring requires Point/Segment
 strategy, not Point/Point strategy. If you passed:

 {{{
     bg::strategy::distance::cross_track<>(earthRadius)
 }}}

 the result would be correct.

 We have a few options:
 1. As you suggest somehow pass radius from input strategy into the
 Point/Segment strategy created in `backward_compatibility.hpp`. This may
 be problematic currently.
 2. Remove backward compatibility since it allows to use strategies
 incorrectly.
 3. Something else?

 Barend do you have a preference?
