We need to do whatever the CMake equivalent of "please turn large file support on" is; if we're already doing that, it appears not to be working.  (I infer from "'gint64' (aka 'long long')" that this is a 32-bit build, and the 32-bit platforms are the ones where Large File Summit hackery is needed to support Large Files - well, except for 4.4-Lite-derived 32-bit platforms, where off_t is *always* 64-bit.)

Thanks to your advice the problem should be properly fixed now.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
