Thanks. Then BSD extended the contract. That's still a problem of musl
and glibc. The API is deficient without setprogname(3), and should be
fixed. I think libc should either drop err.h and let another library
take ownership of the API, or add a way to configure it, hopefully being
compatible with the BSDs. No?
Have a lovely day!
