clearcase and inodes

[Leisner, Martin]

I'm using diff 2.7.1 (but newer ones probably work the same way).

On clearcase trees, the fact that two directory have the same inode
number doesn't mean the
children under them are the same (this I found by inspection).

Hmmm...the inodes are the same, so diff thinks "I'm done".

A brute force approach would be to have an option to turn off the inode
compares.

(After using clearcase for nearly a year, I'm NOT a fan of it).
