John, I see the difference between your and mine build and it looks to 
be simple miscommunication between us.
You simply didn't have a 64-bit enabled on your 3.8.2 build:

ans = no

I suppose you only have specified --enable-windows-64 but not --enable-64.
That means you have an Octave version that runs only on 64-bit windows, 
but can't use arrays > 2 GB.

Try a build with --enable-64 (that automatically implies 
--enable-windows-64) and then try to install OF-image, ltfat, odepkg, 
fl-core and netcdf.
