so the compile fails in servers/slapd/back-dnsserv with the following:

search.c: In function `dnssrv_back_search':
search.c:186: error: `ad_dc' undeclared (first use in this function)
search.c:186: error: (Each undeclared identifier is reported only once
search.c:186: error: for each function it appears in.)
search.c:207: error: `ad_associatedDomain' undeclared (first use in this
function)
make[3]: *** [search.lo] Error 1


As a temp fix (as I do not need the dnsserv stuff for a few weeks), I added
these two variable declarations in the dnssrv_back_function under the else
directive (circa line 174):

        AttributeDescription *ad_dc = NULL;
        AttributeDescription *ad_associatedDomain = NULL;

and it got it to compile.  Obviously the if clauses that check the value of
ad_dc and ad_associatedDomain will always go through though, so my fix is
unlikely.
