I've made configure check for both struct ip_mreqn and struct ip_mreq,
and if it finds neither then the code in socket-io.c is ifdeffed out.

I want to set _XOPEN_SOURCE globally for hpux builds, and the place to
do this is in the platform-specific sections at the top of configure.in.

Theres a default section that says:

	*)
		AC_MSG_WARN([*** Please add $host to configure.in checks!])
		platform_win32=no
		libdl="-ldl"
		;;

which should be triggered on hpux, so do you have a set of defines,
linker options etc that are needed for building threaded code on hpux? 
When we have the hpux stanza, then I'll make it add _XOPEN_SOURCE and
add the _EXTENDED define in daemon.messages.c.
