Does anyone know how to compile gcc-3.4.6 for the

the --target=pdp11 switch and the compiler runs for awhile then breaks. The
output says it's bulding for a pdp11-unknown something so there maybe
something I'm not using.

And there's another issue: *which* PDP11? I have a MINC-11 that was
upgraded with an 11/23 CPU, as many were. I managed to get my hands on
the original MINC software, and it would not run. It's been a while
since I did that so I don't remember the exact instruction on which it
choked (with an illegal instruction trap). But I dropped in an 11/03
CPU and all ran fine. I found a helpful matrix in one of the DEC
handbooks that outlines just which instructions were changed between
several of the Qbus processors, anyway.
Imagine the number of compiler switches.... -- Ian
