Initialization sections may be used to register things. For example if 
you include the interfaces unit, then you create the WidgetSet object 
for the chosen widgetset. No other code is in that unit, but it is 
needed for proper working of an LCL application (remove the interfaces 
unit from .lpr file to see what I mean). So it would be wrong for the 
compiler not to call the initialization section of that unit, even if it 
is not used later.
