Windows 7, cygwin > 1.4.1 symlink issue

[Roland Roberts]

I have one machine, a company machine which makes it hard to post 
details, which is running Windows 7. We run cygwin as our development 
environment for Java, but Java is installed as a Windows program. The 
scripts that do the builds are bash scripts that pull down updated code 
from svn, then run unit tests. All of the cygwin bits work fine, but 
when Java is launched to run the unit tests, it runs into problems with 
reading files that were created as symlinks in cygwin. Note that this 
does *not* happen with cygwin 1.4.1, but does with higher versions (up 
through 1.7.1).

Possibly related, the permissions on installed files is odd if I roll 
back from > 1.4.1 to 1.4.1. The files that were updated with the later 
version can't be deleted. The permissions on, for example, an Emacs 
upgraded under 1.6.1 or 1.7.1 show "Unknown User" when I downgrade just 
cygwin and I can't run it. I have to upgrade cygwin, uninstall Emacs, 
downgrade cygwin then reinstall.

Other users in the company have had their machines upgraded/replaced 
with Windows 10 and don't seem to have this issue. Eventually, mine will 
be replaced as well, but in the meantime, later versions of cygwin can't 
be used.
