We will be setting up a SG 4D/340S running IRIX 3.3.1 and would like to know of sites from whom we can ftp the patches for: plp, cops and gnuemacs. Thanks in advance.

I think it's time to re-post the patches to Gnu Emacs 18.55 that allow you
to build and run it on Irix 3.3 and later:
Between 3.2.* and 3.3, the loader no longer ignored errors in the a.out
header that GNU Emacs took advantage of. I am told that that was un-done
in 3.3.1. It mostly meant that a _stripped_ 3.2 binary would fail to load
under 3.3, an unstripped one would appear to work fine. In addition, a
change was made in libc.a for POSIX compliance: getwd() was defined, but
in terms of getcwd() (or something like that). Emacs assumes by default
that a system doesn't have getcwd(), and defines one interms of getwd().
Hence, an inifinite recursion loop is generated, and Emacs core-dumps when
it hits process limits while building the final executable.
2 solutions:
1) Get 18.56 (should be available any day now, I understand) -- I tested
it to ensure that it compiles out-of-the-box under 3.3.1.
2) Add the following lines to .../src/config.h:
/*
* Irix 3.3 defines this, and causes an infinite loop when trying to dump.
*/
#define HAVE_GETWD
and (if you are running 3.3 unstead of 3.3.1), apply the following patch
to .../src/unexmips.c (a 1-line change):
