Yeah, silly cut and paste.  The original makefile had two .h files;
I cut it down to 1 but wasn't quite consitent.  The problem happens with
either of them of course.

Yeah,  a couple of years ago we had problem with one version of diff,
it thought the files were identical because of a similar problem.
We found the newer version you quoted from below fixed it, they added an
extra check I think.

Out of my hands that is!  (The makefile is part of a tool that has to
work with the way things are done here...)

|    inode) pair to two distinct files, including:
| 
|    - GNU/Linux NFS servers that export all local filesystems as a
|      single NFS filesystem, if a local device number (st_dev) exceeds
|      255, or if a local inode number (st_ino) exceeds 16777215.
| 
|    - Network Appliance NFS servers in snapshot directories; see
|      Network Appliance bug #195.
| 

Yeah,  that's the fix I was thinking of.

|    - ClearCase MVFS; see bug id ATRia04618.

Oh, that's useful,  thanks.   We'll have to see when (if?) it gets fixed...

Thanks for the feedback.
