complete dbus segfault backtrace 

dbus-1.4.0 fails to compile by default on Solaris with below shown errors. I observed that this was failing because some of the struct/union member's were available conditionally in sys/socket.h. I was able to get past these errors by patching dbus/dbus-sysdeps-unix.c with below shown patch.

This worked well and compilation was successful but after this I found issues with dbus while using it. one of my application's is segfaulting. I have posted backtrace of the core file which indicated an issue with dbus especially at _dbus_read_socket_with_unix_fds at line number 292 of dbus-sysdeps-unix.c   

compilation erros.

Can some quickly look at this and help me here?  

Thanks
