I've downloaded 2.1.19 and have modified my make_sparse to
work with it. I got binary operators to work ( * .* \ == ),
but got errors with unitary operators ( x' -x etc.).

Then I tried this with the make_int.cc from 2.1.19 and
found the same problem. 

A:> cp /usr/src/octave-2.1.19/examples/make_int.cc .
A:> mkoctfile make_int.cc
A:> octave -q
octave:1> x=make_int(4);y=make_int(5);

octave:2> x==y
ans = 0
octave:4> x'

octave:4> -x

I suspect that there is a bug in make_int.cc in 2.1.19
