This code is a user library. It doesn't require anything not already in cygwin1.dll. While it'd be _better_ to integrate this functionality into the core, of course, doing so isn't required to make the feature work: that's why I posted to this list. > However, you should check out the copyright assignment requirements [2] > if you want the code to make it upstream. Of course I'll assign copyright if the code makes it upstream in some form.
