Dunno! My last project there was to add support for one of the TI DSPs, but as I said, that's decades past now.

Anyway, I think there are two takeaways:

1. There probably do exist non-8-bit-byte architectures targeted by compilers that provide support for at-least-somewhat-recent C++ versions

2. Such cases are certainly rare

Where that leaves things, in terms of what the C++ standard should specify, I don't know. IIRC JF Bastien or one of the other Apple folks that's driven things like "twos complement is the only integer representation C++ supports" tried to push for "bytes are 8 bits" and got shot down?
