Hi Joseph,
I have seen no comments from the mn10300 maintainers. I think abbreviating const char * is actively bad. Cstar - defined for mn10300, whose maintainers haven't commented
Whilst I am not a maintainer for the MN10300, I am the author of that bit of code. I can say that I have no objections to removing the use of Cstar, it was just a syntactic shorthand, and not a very nice one at that.
If you do not get a response from Jeff or Alex you might like to ping rth, as he has been actively reviewing my recent MN10300 patches.
Cheers Nick
