Solaris 10 Update 5 has it as well as the publicly released OpenSolaris.

Here is the output of your program on an internal release of Solaris
that I run on my workstation:

$ ./pktinfo
SunOS 5.11 snv_147
IPV6_RECVPKTINFO defined
IPV6_PKTINFO defined
IP_RECVPKTINFO defined
IP_PKTINFO defined

The other releases of Solaris that I mentioned should produce similar
results.
