| That's what you want.  INADDR_NONE should be defined as -1; that's what

Actually inet_addr() is supposed to return in_addr_t:
    [http://www.opengroup.org/onlinepubs/000095399/functions/inet_addr.html]
and in_addr_t is uint32_t:
    [http://www.opengroup.org/onlinepubs/000095399/basedefs/netinet/in.h.html]

so really:

#ifndef INADDR_NONE
#define INADDR_NONE ((in_addr_t)-1)
#endif

but then you need to make sure that in_addr_t is defined :-)
