    People are welcome to implement their own string handling functions,
    but we aren't going to put things into libc that are not standardized
    across multiple platforms.
In neither case (memdup nor my own kit) was I talking about inclusion
into libc, which I consider completely useless because not everyone
else will do it, so it'll have to be duplicated in 'portable' code
bases anyway. I was merely saying that for Andreas' usage, he can
easily find a better way, and I gave my example of a clean foundation
for efficient and scalable memory referencing, which happens to work
well for byte-per-char strings too.
