[PATCH] Fix ldap_set_rebind_proc detection with gcc 4.6

[İsmail Dönmez]

Hi;

Gcc now correctly warns for set but unused
variables(-Wunused-but-set-variable) and this causes a compile error
while detecting
ldap_set_rebind_proc argument count because the tmp variable is set but
unused. Attached patch fixes this by simply using (void)tmp; to make gcc
happy.

Regards,
ismail
