Update GCC from 2.95.2: 2.95.3, 3.1.1, or 3.2?

[Tim Wunder]

OK, Caldera eW3.1 base install (but I guess by now it's a far cry from that...) with updated kernel 2.4.18 with preepmt patch, and glibc 2.2.5.
I've been having a persnickety atexit problem with many of the programs I've been trying to compile of late and my latest information tells me that a likely fix is an upgrade of gcc. I currently have gcc-2.95.2 as provided by Caldera for their eW3.1.1 product. 
So, my question is:
Should I update to gcc 3.2, 3.1.1 or stick with the 2.95.x tree and use 2.95.3?
I suppose I *could* install multiple compilers and figger this out on my own, but I was hoping someone with more experience would offer a clue. I'm leaning toward trying 3.1.1.

Thanks, 
Tim

PS There doesn't appear to be a Step on updating gcc. Is there one tucked away somewhere that I just can't find? The instructions on the gnu site are, um, thorough (ly confusing...)
