DragonFlyBSD

There is a gethostbyaddr_r in src/lib/libc/net/gethostnamadr.c which looks
provisional and should presumably not be used for productivity purposes.
The following simple program
---
int main() {
gethostbyaddr_r();
return(0);
}
---
compiles without errors, but is this really intentional? Thus pretending
to have a working gethostbyaddr_r is at any rate confusing for configure
scripts from 3rd party software which check for the presence and usability
of such function, the correct number of arguments cannot be determined.
The effects can be seen, for example, from running 'bmake configure' for
www/privoxy. That's not a fatal error in the case of privoxy, but the
program runs slightly misconfigured on Dragonfly and fills its logs with
complaints. Maybe an incomplete gethostbyaddr_r should better remain
invisible (at least on the RELEASE branch)?
