This is a RFC on a change to sys_errlist for errno = 0.
On Linux, if perror() or strerror() is called with errno = 0, the resulting
string is "Success".
On FreeBSD, the resulting string is "Unknown error: 0".
I think that FreeBSD's output is unintentionally confusing, as errno = 0
implies success.
The following patch will change the output to the Linux behaviour.
I appreciate any comments.
