I'll try to connect in IRC to understand this need a bit better.

It would not really be any problem to provide some additional Win64
binaries within the existing installer as packages.  Perhaps these
packages would (for now) appear only in the Win64 group so as not
to confuse people just interested in 32bit.

We could put the unpacked stuff into:

There is no build mechanism per-se for OSGeo4W.  Individual packagers
build their packages on their own systems, and then package them
up in the proper directory structure as a .tar.bz2 file and upload it
to a particular place on download.osgeo.org as per:


So, if you are keen on the job, I would not object to some Win64 packages
within OSGeo4W. I'd be happy to help explain packaging, etc.
