For this, a 64-bit MSYS is required. If someone who has a 64-bit Windows 
system can take the initiative on this, I would be very grateful - I have 
no access to any such system. Brian Ripley and Uwe Ligges have been in 
touch with me on this, and so far have put it aside until packages without 
external dependencies are done. It really does depend on our community 
building PROJ.4, EXPAT, and GDAL from source under 64-bit MSYS on a 
Windows 64-bit system using the same build train as other w64 packages, if 
we want it done.
