That doesn't have anything to do with browsing (smbd doesn't browse
anyway). The 3.3.x code doesn't have the symbol _nss_wins_freebsd_gethostbyname_r
in it at all, so this doesn't look like our code.

Can you find out what package installed the libnss_wins.so library ?

Looks like it might have come from here:

http://www.nabble.com/-PATCH---FreeBSD-1--nss_wins-support-for-FreeBSD-td23910214.html

which is code that never made it into the main Samba tree. Is
this part of the Samba FreeBSD ports system ?
