This is a configure problem. I can't remember the details, but I believe
undefining some ?_PTYS define in config.h will allow SSH to build and run.
Ralph would know better. I'll see what I can find out when he gets in.

I've seen this before if libIIOP is from Orbit. There is a fix in the RPM on
NetWinder.org I believe. The shared library links against a static library,or a
set of object file which haven't been compiled with -fPIC.

Actually this is extremely difficult, as it is very difficult to allocate memory
for the PLT stubs, given the way ld-linux.so.2 loads the shared libraries. It
is impossible to do on the fly, and requires modifications to the tools to
ensure there is space allocated at link time. If I have to modify the linker to
do that, I might as well modify the linker to convert the reloc to a PLT32 reloc
and avoid the problem all together.

I don't like the sound of that, I'd like to hear more about this problem. Can
you fill me in or send me a test case of code you think is broken? While were
on the topic of broken linkers, the latest binutils linker seems to be broken.
Andrew sent me a test case with behaviour I just don't understand yet.
