Simon, all warning will go away if you enter CDL for LWIP_ERR_T, look,
please, at lwip/err.h. By default that is signed char (?!), so its
capacity is quite overflowed. I just tried an ugly addition in err.h

#define LWIP_ERR_T unsigned int

and that fixed all gcc complains in socket.c. I checked it, i.e. with that tweak
all package is compiled silently (arm-elf-gcc 4.3.2), just alone warning:

sequential.c:113: warning: âset_ip_addrâ defined but not used
