After much fighting, I have managed to build xgcc, aka the bootstap compiler.
I used the headers and libraries from 4.1.5, and used a gcc 3.4.3 compiler on AIX 4.3.2 to compile gcc 3.4.6. I wrote a wrapper for "cc" that did alot of fudging to get the builds to work.
This would be a good time for somebody to then take what I have done and build the remainder on a real AIX 4.1.5 box.
Chris, are you game? How would you like to receive what I have done so far?
The cc wrapper wot I wrote:
