compiling very new gnu software on a very old machine

Hi folks,

Just out of curiosity, I'm trying to compile some new gnu utilities on 
my very old 3/80 machine. Unpacking the tar, running configure and then 
make doesn't seem to do it anymore. I'm no C expert and I'm not sure 
what's going on, other than maybe there are some options I need to pass 
to configure to make it deal with an 18 year old OS.

Machine is a Sun 3/80, 64MB ram, running SunOS 4.1.1U1

I have GCC 3.2.3 installed from a pre-built package.

So far I've gotten bash 3.2.0 and grep 2.5.1 built, but a bunch of 
others (coreutils, binutils, texinfo, make, etc.) won't build. And yes, 
some won't build because of dependency issues...

any pointers on how to get things built on this old box would be helpful.

As an example, I'm getting this from building binutils:
