Basically, "stuff from mingw-w64.sf.net" The middle piece of the triplet is the vendor tag. We at mingw-w64 are the vendors. We support win32 and win64, for both host and target. I admit it's confusing, but we didn't come up with a better name fast enough. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
