I do not see the point, not for the choice of library version.
OpenLDAP #includes <db.h> whatever version is chosen, except 1.85.
Nothing constructive can be achieved by selecting another library
version than that of the #included file. So I think configure should
#include <db.h> and extract the library version number from that.
There can be a problem if the <db.h> in the include path should be used
with -ldb-43 or -ldb while OpenLDAP picks a -ldb43 which is installed
later in the library path. So such an option could still be useful.
But this would be much rarer than the version mismatch problem people
keep running into.
