But if you saw my libxine's config.log, there is a check in its configure script for presence of _environ variable, which is not present in 7.0-RELEASE at least. So, I'm wondering, why no one else received this error while building libxine port. > 2) Your code assigns environ = NULL, which is why I felt the above > commit has relevancy to you.

So, should I file a PR for this ?
