In general, it is considered poor netiquette to send a screenshot when a
textual transcription will do.

In this case, your version of diff appears to have been built for
Windows.  Which distribution did you get it from?  Cygwin, mingw,
Interix, something else?  It may be that your particular pre-built
binary is missing some prerequisite libraries, which would be an issue
for your distribution to resolve, rather than upstream diffutils.

Also, the ClearCase MVFS file system is notoriously buggy on Windows.
Cygwin has lots of nasty hacks to work around ClearCase's quirks.  If
you are using the cygwin version of diff, then you are better off
reporting to the cygwin list, to see if yet one more hack will be
required.  Otherwise, I would suggest raising a bug report with the
folks at IBM about their ClearCase product not obeying Windows file
system conventions, although given that ClearCase is not open source, I
can't promise any chance of a decent resolution with that approach.
