All, I'm not certain if rebase is being actively maintained, since the last release was over a year ago. If anyone is, I have a patch for rebaseall that adds compiled octave shared libraries (*.oct) to the list of things that rebaseall can rebase. This should make rebaseall work with octave installations.
Thanks, Jim Phillips, Cygwin Octave maintainer
