Hi Corinna,

I noticed the problem that /cygdrive/c/Windows/System32 directory
can be no longer accessed from 32 bit cygwin (WOW64) after the
commit:

commit 456c3a46386f38887407603b2c64b7f63a4871c5
Author: Corinna Vinschen <corinna AT vinschen DOT de>
Date:   Mon Apr 19 14:49:14 2021 +0200

    Cygwin: path_conv: Try to handle native symlinks more sanely

    For local paths, add a check if the inner path components contain native
    symlinks or junctions.  Compare the incoming path with the path returned
    by NtQueryInformationFile(FileNameInformation).  If they differ, there
    must be at least one native symlink or junction in the path.  If so,
    treat the currently evaluated file as non-existant.  This forces
    path_conv::check to backtrack inner path components until we eliminated
    all native symlinks or junctions and have a normalized path.

Reverting this commit resolves the issue.

64 bit cygwin does not seem to be affected. Could you please
have a look?
