Funny, I actually thought that the unzipping code is the uninteresting
part, while the BFD code could hope to be revived. From what I've seen
it is much nicer to use than the ELF parser we currently use.

The patches were also ment to address the complexity^Wsheer size of
the code. That is why I wanted to remove them, #ifdef'ing it out has a
cost, not a runtime one but for anyone hacking on /hurd/exec.

Out of curiosity, why do you consider this feature interesting?
