These are quite normal warnings for the IRIX linker. Which gcc version do
you use (try "gcc -v" to find out)? Gcc 2.95.2 behaves much better than
gcc 2.8.1, so try to upgrade to gcc 2.95.2. Gcc 2.95.2 does a much better
job on optimisation, it is at level with the SGI MipsPRO compiler.

So far, the WARNING 85 haven't bit me, and I use GTK on IRIX for over a
year. If you are really annoyed, edit the gcc specs file, find the '*link"
line and change "-woff 131" into "-woff 131,85". Watch out: in this way
you also won't be warned about symbol clashes that *will* bite!

Another hint: some morons at SGI decided that /usr/local was a nice place
to put configuration files in, so be careful when installing local
software in it! (yes: been there, done that)

http://gcc.gnu.org/ for gcc 2.95.2

http://freeware.sgi.com/ for IRIX freeware

http://www-it.et.tudelft.nl/~erik/gcc/ for gcc 2.8.1 compiling
instructions and hints. gcc 2.8.1 on freeware.sgi.com was built using this
rules.
