Quick reaction, reverting fixes the problem when compiling with FPC 2.6.2 but broke it for FPC trunk.

To not repeat myself please read my note in  http://bugs.freepascal.org/view.php?id=24059  I have been a little busy and the fix for carbon was delayed because it seemed to me that it will be a better fix to handle this in LCL package using build macros, defining globally a conditional, HAS_INHERITED_INSERTITEM for example, if fpc version is less than 2.7.1 (it is needed at least for Carbon and Qt (and possible gtk2 too according to issue 0024154)).

If that is not a viable solution, I can fix it the same way than for Qt.
