You are probably right. I downloaded source code from https://www.gaia-gis.it/fossil/spatialite-tools/index and it looks to me that spatialite_map_c has code for building geometries. I cannot compile anything myself but once new version of spatialite tools are available as Windows binaries I will have a try.
