When built with gcc-5.1.0, Errno.pm doesn't define any errno constants. I believe this is because cc -E now outputs line breaks where it didn't before (see http://www.openldap.org/its/index.cgi/Build?id=8056;page=1 for the source of this guess). The attached patch fixes it for me, but I'm guessing it's not very portable.
