Platform-dependent configure templates

[Adam Tkac]

Huh, and what about next spurious statement (from config.dlz.in):

        for d in $odbcdirs
        do
                if test -f $d/include/sql.h -a -f $d/${target_lib}/libodbc.a
                then
                        use_dlz_odbc=$d
                        break
                fi
        done

What will be done if we have only shared library? Build will be 
successful but configure breaks it because we don't have static archive 
:( We really should use ac_try_link instead... (or some other macro)
