I am certainly aware that they exist,
but I don't have access to any non Linux box.
I guess I should have clarified the intent of my original patch submission:
it was meant to raise the fact that this glibc deprecation exists,
and that it ideally should be addressed at some point.
Given my inexperience with the intricacies of cross-platform stuff,
I defer the exact solution to more experienced hands.
