I confused the H8 backend with the V850 backend, sorry for that. I have realized later that the V850 backend is the one where the conversion has been completed. > I'll walk you through one example from the H8 port.

I will be going through this over the weekend trying to understand the details. > My son is definitely still interested.

I don't think there is a conflict of interest in any way. It's perfectly fine to pick up the task yourself and receive the bounty. The community doesn't really care who gets the job done. And since I don't assume your employer is paying you to work on the m68k backend, it's absolutely okay in my opinion to be paid for the task, time isn't free, especially developer time. It's very valuable to everyone in the various m68k communities to have an up-to-date version of GCC available which is why so many people have donated for the cause. Thanks a lot for your time and input! Adrian -- .''`.
