I've used GCC 1.37 (loaded of dsrgsun.ces.cwru.edu) as a cross compiler 
hosted on a SUN4 running SunOS 4.0.1, no problem. The only problem was
an alignment problem in the tool "size", j.bammi sent me a pacth, I don't
know if the patch made it into the distribution (or when).

The size assumptions are OK for running on a SUN4 (or so it seems).
I compiled the doodle demo program, and the PCCTS compiler-compiler tool.
These worked straight out of the box. The only thing i don't think 
I tried was floating point. As the SUN uses IEEE itself, it should be okay. I 
haven't got the executables for the SUN anymore, so I can't check it..
