Until some time ago (several months at least) it was possible to build
Octave natively on Windows using MXE. But it took AGES - while a cross-build
on Linux took ~ 3 hours, a native build on Windows easily took 24 hours or
more on the same multiboot box.

AFAIK no one has attempte d native builds lately and it is uncertain if it
still works.
