ssh 3.1p1 problems on SX-6...

[Wendy Palm]

SX-6 is the NEC machine followon to the SX-5.  SuperUX is the OS.
Cray Inc currently provides support for some of these machines in the
US and i have a openssh port of 3.4p1 that runs on one.
we haven't run into this particular problem, so our port must be more
complete than manish's.

be a bit patient and i'll update it to 3.5 and provide our patches for manish to try.
