Quick reminder for the archives: the reason for the USE_POINT_Z_M option 
is that there is (or at least used to be at the time) a non trivial 
performance impact (15%-50% performance hit) likely related to the 
increase in size of the pointObj struct when Z and M are added:

https://github.com/mapserver/mapserver-import/issues/1244

It may be nice to have some updated benchmarks comparing with and 
without USE_POINT_Z_M with recent releases, but I just wanted to point 
out that if one cares about performance and doesn't need the Z,M then is 
preferable to keep this option turned off in their builds.
