Thanks a lot, good to know. The signatures of those functions have not
been changed for at least 12 years.

Potentially stupid question: Why are Wine's "Windows" paths using
unicode (wchar) while the unix counterparts are not (char)? It's the
same both in the kernel32 and NT APIs.

I can, but this can be agonizingly slow - compared to a direct call to
the above mentioned APIs. Starting a complete new (sub-) process seems a
bit of an overkill for this kind of task.
