I performed a cygwin update today, and was confronted with an MD5 
failure on one of the packages.

The package was vim-7.1-1.tar.bz2 downloaded from mirrors.dotsrc.org

As the package installed, I saw some strange behavior, I'm worried it 
might have been some kind of trojan.

I saved the hacked package file in case a cygwin developer wants to see 
it.  I was able to get the vim-7.1-1.tar.bz2 from another server with 
the correct MD5.

The correct md5:
df543517110fa14fcc13a207ef721459 *vim-7.1-1.tar.bz2

The md5 of the hacked package:
43f00ebc2964d7c84fde7b7150f1b3a5 *vim-7.1-1.tar.bz2-HACKED


I also have a complaint:  the dialog that notifies the user of the 
failed MD5 is not well designed.  The dialog asks "Do you want to skip 
the package?" and has a yes and no button.  I read it quickly and 
pressed no before thinking about it, the package went ahead and tried to 
install.  I think there should be a little more effort to restrain the 
user from performing a dangerous action such as installing a package 
with a wrong MD5.
