1. I don't recall any consensus on abandoning QImode!=8bits.

I don't think this issue is relevant in terms of considering whether or not to obsolete the C4X port. Whether or not QImode is always 8 bits is a fine debate, but it's a separate debate. I certainly was not taking a position on that debate in approving the obsoletion request. Independent of the size of QImode, I think that everyone agrees that supporting targets with > 8-bit minimum addressable units is a useful thing.

2. tic4x-gcc-3.4.x is buildable, tic4x-gcc-4.x had never built.
i.e. actually a regression has occurred sometime between 3.4.x and 4.0,
which had slipped through GCC-regression testing cracks.

Yes, and that is evidence that the platform is indeed obsolete. Nobody was willing to invest in making it work in GCC 4.0.
