So, does this work?
 
#if defined(__hpux) && !defined(_XOPEN_SOURCE_EXTENDED) 
        int socklen;
#else 
        socklen_t socklen;
#endif 

Sorry,^WThankfully I don't have HP/UX so I can't test. Having the same
symbol in two different libraries with different ABI is not the best
solution. Why aren't they using symbol renaming?
