-From a559550c8e2d162735ff8a43de6dc59af71cf3df Mon Sep 17 00:00:00 2001

-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.
