Does anyone out there have Epoch 3.2.3 running on an SGI Challenge machine
with the IRIX 5.2 operating system?  If so can you or anyone else suggest which
configuration files to use and what modifications are needed to get it running
on that machine.  We have tried m-riscos.h and m-mips.h but they keep trying
to use BSD include files and libraries.

I have seen mail about Epoch 4.2 on the network and should probably upgrade
to that or possibly to Emacs 19.  We have added some additional edit modes for
writing C++ code and other things which we would also have to upgrade.  Does
anyone know what kind of problems should be expected when moving elisp code 
from Epoch 3.2.3  to Epoch 4.2 or to Emacs19?  From where is the best place to
download the Epoch 4.2 or other latest version of Epoch?

Any help would be greatly appreciated.  Thank you in advance.
