Could you please try the patch from Alexander Gattin at
https://savannah.gnu.org/bugs/?29451 and see if that helps with this
problem?

It looks like defining _XPG4_2 is not the right way of doing things
(http://stackoverflow.com/questions/1034587/how-does-xpg4-2-and-other-defines-work-on-solaris).
Can you try out the suggested 'proper' fixes and see if that works for
you?

For me, CMSG_LEN seems to be defined in /usr/include/linux/socket.h. Is
it defined elsewhere on Solaris 9 (or just not defined anywhere at all)?
