For linux-to-windows cross-compilation using mingw, I find "M Cross
Environment" -- http://mxe.cc -- very useful and very easy. It
already supports netcdf (and a ton of other useful libraries, see
http://mxe.cc/#packages) out of the box.
In my experience, it makes cross-compiling "just work", highly recommended!
