Saying &#x27;runs on Cygwin&#x27; is a little obtuse when these packages are built with mingw-w64 to run on win32. The packages won&#x27;t understand cygwin paths nor cygwin symlinks, and good luck linking to these libraries from a cygwin program.<p>EDIT: Oh, i think the copy intended to mean &#x27;can be cross-compiled from a cygwin environment&#x27;. Leaving comment for posterity.
