John,

No MapServer is built with exactly the same build of GDAL found in OpenEV_FW_163.
I would add that the way MapServer is currently built against GDAL on windows,
a bunch of the OGR stuff is statically linked into mapserver executables, as
opposed to being used from gdal11.dll.  Because of that, it is generally not
sufficient to replace a gdal11.dll to upgrade mapserver to a new/different
version of OGR.

This is something I would dearly like to fix in MapServers' windows build structure,
but to accomplish it (practically speaking) we almost need to rewrite the
mapogr.cpp module to use the OGR C API and to reexamine the use of some of the
style related definitions in mapogr.cpp.  The use of static OGR libraries in
MapServer causes me no end of headaches.

Best regards,
