[R-sig-Geo] rgdal 64bit Windows version?

[Alex Mandel]

It might be wise to collaborate with the OSGeo4W project.
http://trac.osgeo.org/osgeo4w/
Many of the developers who deal with proj,gdal etc are behind this
project and there's a lot of good knowledge about MSYS in the group.

A 64bit version of OSGeo4W binaries seems like a good goal to introduce
that will directly lead to 64bit support in RGDAL.
