I have found that ISC's libbind 6.0 does have this function, but for some
reason, this was not being detected and the dummy sub routine was being
compiled in regardless. Commenting out the stub for freehostent() locally
fixed the problem.

The milter library of Sendmail needs to be fixed to detect the presence of
this (separately from getipnodeby*()) and conditionally compile around
this. The following commented assumption is WRONG:

/*
** Stub routine -- if they don't have getipnodeby*(),
** they probably don't have the free routine either.
*/

Conditionals: #endif /* NEEDSGETIPNODE && NETINET6 */

The conflict shows up in a failed compilation of milters, including
dkim-filter (where I saw the problem), and the older dk-filter, where the
linker complains about a redefintion of the size of the routine (5 bytes
vs. 271 on my system).

I have Sendmail version 8.14.4, compiled from the source. I have not
checked 8.14.5 alpha 0 for the problem. As noted by the conditionals, this
may only appear on IPv6 enabled systems.
