I see DirEntryStack aStack; in DirEntry::ImpParseUnixName in
tools/source/fsys/dirent.cxx which suggests that it might still be in
use. "ImpTryUrl" however seems unused.

Well, its the quickest way to find out if it might be used. Clearly if
it does build without it it might be the case that its used under e.g. a
different platform or different debug level, suggesting it needs to be
ifdefed inside the same guards as its users. In this case I think it
looks used, but quite probably ImpTryUrl isn't and can be removed, which
might mean that various bits of DirEntryStack might also be unused.
