Argh, I keep forgetting `dlopen` does not set errno (at least its not guaranteed by the standard).

Ok, in this case, I would not analyze the string either because it may be locale-dependent.

Never mind then; I'd thought this would be easy. One could probably use load() instead of dlopen() on AIX, but that change would require more investigations to see if load() and dlopen() are equivalent.

Okay, in that case just skip the errno test and call the second dlopen directly. Lets hope for the best then.
