It should probably be ((in_addr_t) -1) since the type may be
unsigned long (e.g. HP-UX) or unsigned int (e.g. Digital UNIX).
But even on HP-UX 10.10 you have to define _XOPEN_SOURCE_EXTENDED
to get in_addr_t defined. Maybe 0xFFFFFFFFu would do the job
(at least keep the compiler from complaining about having a negative
signed int constant expressed by a positive value on 32 bit systems),
or else inet_addr("255.255.255.255").

BTW: On HP-UX 10.10 there is in netinet/in.h:

#ifdef _XOPEN_SOURCE_EXTENDED

#ifndef _IN_ADDR_T
#define _IN_ADDR_T
typedef unsigned long in_addr_t;
#endif /* ! _IN_ADDR_T */

#endif /* _XOPEN_SOURCE_EXTENDED */
