update via setup.exe removed NTFS junction?

[Robert R Schneck-McConnell <schneck at math dot berkeley dot edu>]

For reasons which are now obscure to me, I had set up an NTFS junction
point from /var (c:\cygwin\var) to some other partition.  Could have
done it with mount, but I didn't.

Just today after running setup.exe and getting cygwin-1.5.7-1 and a few
other things, I found that /var was now an ordinary directory with
the only contents the subdirectory cache (with empty subdirectory man)
and the subdirectory log (with setup.log and setup.log.full).
Luckily my mail spool et al were still intact at the old junction
target.

Can anyone divine what happened?  Cygcheck output attached, in case
it is useful.

Robert
