First uname and compiler versions:

%uname -aR
IRIX64 banshee 6.5 6.5.11m 01101246 IP25

%cc -version
MIPSpro Compilers: Version 7.3.1.2m

I have just recieved 7.3.1.3m from SGI, but cannot update compilers until I've
had a chance to announce to all developers that the change is coming, and when.

%cat /etc/compiler.defaults
-DEFAULT:abi=n32:isa=mips3:proc=r4k

The above to build the binaries 32bit, as I have Indigo R4000 and Indy R4xxx
machines I have to support as well.

%gcc -v
Reading specs from
/usr/local/gcc-2.95.1/lib/gcc-lib/mips-sgi-irix6.5/2.95.1/specs
gcc version 2.95.1 19990816 (release)

And now for the make output:

I did a 'gmake distclean' and reran configure allowing autoconfig to find gcc
between these two build attempts.  3.0.2p1 and 3.1p1 fail in the same place with
the same error with both compilers.

And now for GCC:

Any help or pointers are appreciated.
