+Subject: [PATCH] Make sure POLLIN/POLLOUT are not defined
+
+We use select instead of poll, because lwip provides a select via its
+socket API. However, that one also defines a couple of POLL* values,
+which lead to a compiler error here because you end up with a line that
+says "enum { 0x1 = Element::SELECT_READ" etc.
