I think there is considerable value to having a port to an architecture
that does not have a power-of-two word size, just from a portability
point of view.  And the universe of available hardware for pdp10 is
sufficiently small that it just isn't (and never will be) that much
code to deal with.

I would like to see the pdp10 PCC-based toolchain somehow be integrated
into  That, too, isn't much code, and it can also compile the
i386 port, I believe; there's considerable value to regularly building
our tree with more than one compiler.  Because Caldera released all the
required parts under a BSD-style license it seems basically certain
that this is OK, but I think we are currently awaiting the end of the
idiotic IBM/SCO litigation before incorporating that code into our tree,
on a "belt and suspenders" basis.
