Of course, if you don't care about broken systems (like MS-DOG) not supporting `strerror()` you can just replace `sys_errlist[]` directly (upstream might not accept your patch, but debian should have no problem)

+On the Hurd, `error_t` is an enumeration of the `E*` constants. However, C++
+does not like `E*` integer macros being directly assigned to that enumeration. In short, replace

Those are evil if they don't exist and you want to name a directory this way. For example, `mkdir foobar/` will not work on GNU. This is POSIX compatible. POSIX says that the path of a directory may have slashes appended to it. But the directory does not exist yet, so the path does not refer to a directory, and hence trailing slashes are not guaranteed to work. Just drop the slashes, and you're fine.
