Hi John,
I am a not a Xemacs pro, so I am not too sure of the intricacies. I was able to
build on IRIX 6.5 with out any problems. I just used the default compiler ( cc )
and set the compilation flags to "-n32 -o2 -mips3".
Infact, this was the first machine I tried to install as I have been successful
in installing most of the GNU tools.
with regards,
dhruva
