In Linux you can find those functions in libbsd.

That's 14 years ago. Is Drepper involved in anything anymore?

Well, it was WONTFIXed in 2004, which is just ten years ago: https://sourceware.org/bugzilla/show_bug.cgi?id=178

Maybe it's worth reheating the debate?

The new glibc maintainers have very different opinions, and have reversed many WONTFIXes

Or perhaps we ought to drop this junk already. Musl libc implements strlcpy while being a whole lot less bloaty than glibc.

Which is more than a little ridiculous. I've written code for Arduino and even that has strlcat and strlcpy - in fact, I had to fill in replacements for them in order to port the code to run on Linux.
