bug, but something I hope is just a config switch that Frank can change when he
builds. In the geos_c.h file I see the way to create a point from scratch
is to create a GEOSCoordSeq_create(1, 2) and then add X and Y values with GEOSCoordSeq_setX
and GEOSCoordSeq_setY, then create a GEOSGeom point from the sequence.
However, I get the linker error from Visual C++ Express 2005:<o:p></o:p></span></font></p>
