[Mono-devel-list] Non GCC compiler patch - ip_mreq & HP'sheaders

io-layer/daemon-messages.c needs _XOPEN_SOURCE_EXTENDED for cmsghdr so it
seems impossible to have this compile and socket-io.c at the same time - but
this is the only file that needs it. So an alternative which feels slightly
less yucky is to have _XOPEN_SOURCE defined everywhere by configure

#ifdef __hpux // is this the right symbol? or should it be something defined
by configure.

at the top of daemon-messages.c to get cmsghdr.

BTW - I have seen no answers to my question on the type to use for an int
big enough to hold a pointer - is there an official story on that?
