Re: bitwise xor

[David Bateman]

Where did you get bitfcns.cc? This file exists in octave 2.1.58, but
it doesn't exist in octave-forge. Its existence in 2.1.58 is due to the
fact that 2.1.58 now includes int/uint types and thes ebit operations
can be handled much better than the octave-forge versions. So I'd suggest
an upgrade to octave 2.1.58...

In any case you shouldn't just build parts of octave-forge with mkoctfile.
Often the code contains special cases to allow building with different
versions of octave, and therefore you should run ./configure in the
octave-forge base and then use the Makefile in the directory to build 
the code. If you'd done "mkoctfile bitand.cc" on the octave-forge version
you would have missing out on the links to bitxor, etc and NDArray's
being able to be passed as parameters in these functions.

David
