And before the `dlopen()` call I set `errno` to 0 and directly after I save `errno` into `eno` and give it all the way back to `os::dll_load()`. Evaluating the `errno` directly in `os::dll_load()` is to late with the explanation of the mentioned discussion.

No. This was meant as a sketch for you how YOU can solve the problem without the string hassle.
