With some compilers (e.g. gcc) the order of includes and overloads 
matters. The default comparable_distance() is compiled instead of 
overloads defined by you. You can work around it by first including GLM 
and defining your overloads of bg::comparable_distance() and after that 
including boost geometry, registering point and proceed normally.
