Please remind me where the Windows binary package came from - is it the 
product of your own success with MSYS? Part of the functionality for map 
projections is in the spproj package, another part for shapefiles is in 
the maptools (and/or shapefiles) packages, but no OGR support is available 
elsewhere. Making a new binary build with fresh PROJ.4, shapelib, and OGR 
under MSYS is an option.

In time merging OGR support into rgdal is logical, contributions? The 
rgdal package CVS is also on sourceforge, at:

http://rgdal.sourceforge.net/

The use of sp classes with rgdal rasterobjects is being followed up, so 
doing the same for OGR would seem sensible. Finally, spproj should perhaps 
also be merged with rgdal, since rgdal has an indirect external dependence 
on the PROJ.4 library and metadata anyway. The maptools package does not 
have an external dependence, because the shapelib C files are copied there 
and in the foreign package (for DBF).
