This is the Cygwin ftp repository. Note that, due to excessive download traffic, direct downloads from sourceware.org (aka cygwin.com) are not allowed. Attempts to download will result in a "is marked unretrievable" message. Please use a mirror if you are interested in downloading anything cygwin-related. Refer to http://cygwin.com/mirrors.html for a list of mirrors. Or, better yet, use the cygwin setup.exe program to update your cygwin installation. You can find it at http://cygwin.com/ .
