I'd go ahead and make the attempt, as what you've found looks like a 
generic SuSE / Red Hat compilation for the Linux implementation on IBM
hardware, and you're bound to run into library trouble mixing AIX and 
Linux-built code.

That said, I'm having loads of fun (not) trying to get 4.3 to build on
AIX 6.1; it's not quite as straightforward as I'd hoped. I found a 
build of 4.2.3 here: http://www.perzl.org/aix/index.php?n=Main.Gcc
which makes reference to patches, etc. being applied for an AIX 6.1
build of that release, and I'm working under the assumption that
things will require some tweaking for 4.3 as well (esp. since it won't
build 'out of the box' as it were)...

So IMHO it's worth it, others of course will undoubtedly know more...
