Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=124963

Thank you for the feedback. I have prepended the two new commits that you suggested to the beginning of this merge request. Please let me know what you think.

I have changed it to use strndupW which I think is even less ugly, but if you still want an ext variable let me know; I am happy to add one.

I don't think adding another use case of the non-standard `strndupW()` makes things less ugly. Go back to using `wcsdup()` - it doesn't matter that we over-allocate a little as this is only a short-lived string.
