Just FYI, without the --enable-64 flag Octave the binary installer gets
built fine.

I suspect nsis can't be built with 64-bit indexing. Perhaps this also
applies to other included support programs not linked to Octave, like
ps2edit, ghostscript, gnuplot, ...
If so, would that imply a 32-bit mingw (cross) compiler would also be
required?
