+dnl Unix sockets with long names are problematic because the name has to
+dnl go in a fixed-length field in struct sockaddr_un.  Generally the limit
+dnl is about 100 bytes.  On Linux, we work around this by indirecting through
+dnl a directory fd using /proc/self/fd/<dirfd>.  We do not have a workaround
+dnl for other platforms, so we skip the test there.
