Wrap recv to avoid warnings
Avoid warnings like these by wrapping recv(): CC slirp/ip_icmp.o /src/qemu/slirp/ip_icmp.c: In function 'icmp_receive': /src/qemu/slirp/ip_icmp.c:418:5: error: passing argument 2 of 'recv' from incompatible pointer type [-Werror] /usr/local/lib/gcc/i686-mingw32msvc/4.6.0/../../../../i686-mingw32msvc/include/winsock2.h:547:32: note: expected 'char *' but argument is of type 'struct icmp *' Remove also casts used to avoid warnings.
