I'm not sure this was actually sent so I'm sending it again. 
 
This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.
 
In GNU Emacs 21.2.1 (i386-msvc-nt5.0.2195)
 of 2002-03-19 on buffy
configured using `configure --with-msvc (12.00)'
 
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
 
Ediff no longer seems to be working.  I'm not sure but it may be a cygwin
interaction.   The ediff error message I get is this: 
 
/bin/diff.exe: c:DOCUME~1dashLOCALS~1TempcropSim.java1216IMH: No such file
or directory
 
/bin/diff.exe: c:DOCUME~1dashLOCALS~1TempcropSim.java1216Fgf: No such file
or directory
 

It would seem the directory slashes are missing.
 
Any additional information that is required don't hesitate to ask for.
 
Thanks
 
Dan
