+Subject: [PATCH] Assume that callbacks are not broken in OpenLDAP when
+ cross-compiling
+
+If we do cross-compiling against a known broken version of OpenLDAP,
+we can do `export ac_cv_member_struct_ldap_conncb_lc_arg=no` before
+running configure. This is rather unlikely now, as the test was done
+to detect a bug that was fixed 16 years ago.
+
+This allows the project to be configured successfully when
+cross-compiling, without disabling connection callbacks.
