FYI, I've applied a rather big patch which reintroduced d_ino and which
tries hard to generate correct (aka "identical to stat(2)") inode numbers
for d_ino on all systems.  This includes a slightly expensive method to
determine inode numbers in a couple of situations(*):

- local NTFS on NT4
- remote NTFS on Win2K
- remote NT4/Win2K NTFS on XP and above.

While I tried to optimize the expensive inode evaluation as much as
possible, a certain slow down in the above situations might have been
unavoidable.

For the adventurous of you, try the next developer's snapshot of Cygwin
from http://cygwin.com/snapshots/

(*) For the curious, the above situations are determined by the
    OS support of the FileIdBothDirectoryInformation flag in calls
    to NtQueryDirectoryFile.
