John, UnxUtils doesn't even use SourceForge.net even though they have a 
project there.  The project has an activity percentage of 2.27%.  That 
means they have no downloads, very little page views and little 
support.  The GnuWin32 project on the otherhand has an activity 
percentage of 98.57% with files to download.  You should really change 
your utilities and download from the GnuWin32 project.
