---------------------------+------------------------------------------------
 The CCoordinateSystemMathComparator::SameCoordinateSystem() API allows to
 compare 2 coordinate systems on (mathematical) equality.

 It incorrectly returns [false], however, if the 2 systems to be compared
 are so called "arbitrary system" which do neither reference a datum nor an
 ellipsoid.

 Currently, if none of the 2 is found, the method mentioned above simply
 returns [false], what is not correct for systems like XY-M (Cartesian XY
 meter).
