Hi

I did the change you mentioned but it does not work. Still gives the same
warnings.

It gives these warnings while compiling ogrgeometryfactory.cpp,
ogrpolygon.cpp and ogrgeometry.cpp. Here is the compile command

cl /nologo /MD /EHsc /Ox /DHAVE_GEOS=1 -I..\port -I..\ogr -I..\gcore
-I..\alg -I\inc  -I"D:\Software\VStudio\VC98\ATL\Include" -DWIN32  -I.
-Iogrsf_frmts -I..\frmts\gtiff\libgeotiff    -IC:/GEOS/trunk/capi
-DHAVE_GEOS=1 /c ogrgeometry.cpp

Are all the flags and options correct?

And these are the errors i get at the end when it tries to link:

Any clue?
