Follow-up Comment #1:

Fixed the dns bug, thanks for reporting. That's the problem with having too
many configuration options: you always risk not compiling parts of the stack
after making changes...

I'm not convinced about the socket return value though: As I read it,
ETIMEOUT is a timeout that is returned when
a) connect() fails (no response after x retransmissions) or
b) send() times out
In both cases, the connection is dead afterwards.

Since we only use ERR_TIMEOUT with LWIP_SO_RCVTIMEO when accept() or recv()
times out, EWOULDBLOCK seems like the better error to me (although the
specification doesn't mention which is the correct value since it doesn't
mention recv- or accept-timeout).

PS: The summary is not very informative :-)
