I've checked it with Kylix 3 and there it's indeed also always the  
same order. Apparently I made a mistake while testing. The FPC logic  
of storing the parameters in the rtti in the same order as the calling  
convention uses them dates from before my changes though. I'm not  
aware of any functionality in FPC or the RTL depending on this order,  
so it shouldn't be a problem to change it. Then again, I know almost  
nothing about any functionality using RTTI (other than reference  
counting), so I'll wait with changing anything to see whether someone  
else maybe knows a reason why this should not be changed.
