Ok, I found the problem/bug:
While apr really does transparently convert long paths to the long
format, it fails to do so properly for directory names
(CreateDirectory() requires the long format for paths > 248 chars, while
all others require this only for paths > 260 chars - and apr only does
this for paths > 260 chars).

I've sent a patch to the apr dev list. But this may take a while until
it gets committed and apr has a new release...
