modification history
--------------------
01s,09jan12,h_x Move extern "C" after last header file include.
01r,12feb07,dlk Added prototypes for rtpGetaddrinfoInit() and
rtpGetnameinfoInit().
01q,05oct06,kch Removed h_ttl member from struct hostent for IPNet
compatibility.
01p,06jul05,vvv fixed build errors
01o,29jun05,vvv added getaddrinfo(), getnameinfo(), freeaddrinfo() and
gai_strerror() for RFC3493
01n,28jun05,vvv restored v4mapped
01m,13may05,vvv merged from kame-20050404-freebsd411
01l,20nov03,niq Remove copyright_wrs.h file inclusion
01k,05nov03,cdw Removal of unnecessary _KERNEL guards.
01j,04nov03,rlm Ran batch header path update for header re-org.
01i,03nov03,rlm Removed wrn/coreip/ prefix from #includes for header re-org.
01h,06aug03,nee Accordion Base6 merge from ACCORDION_BASE6_MERGE_BASELINE
label
01g,10jun03,vvv include netVersion.h
01f,12dec01,hgo add support of flag AI_V4MAPPED for getaddrinfo()
01e,20sep01,hgo extensions for IPv6 support
01d,19aug97,jag Added the field h_ttl to the structure hostent.
01c,29apr97,jag fixed include define and added C++ linkage. Changed field
names of struc netnet to avoid conflict with i960 macros.
01b,24feb97,jag changed comment.
01a,26nov96,gnn created from BSD4.4 routed
