Gemacs on a sun - process control

[Edward L. Lafferty]

Has anyone out there ported Gosling emacs to a sun? I have successfully
ported it to 4.2bsd on the Vax and it seems oK on a Pyramid, but I
can't seem to get the process control stuf working on the Sun. I can
start up a process using :shell or <esc>- (altho it gives me two shell
processes and two prompts. I can do the normal things in the shell
but when I try to EOTProcess it with control-D or eot-process it
gives a segmentation violation. I have tried to track down the problem
using dbx but all I can determine is that the EOTProcess returns suc-
cessfully and the system ends up in the header of the sigretro.c file.
(I used sigretro.[ch] to port the signal stuff to 4.2. I suspect that
may be contributing to the problem but why on a sun....and not a vax...?
Any ideas would be appreciated -- especially solutions, but even 
suggestions for tracking the problem..
