[fpc-pascal] Obtain Class hierarchy (in MacPas mode)

[Adriaan van Os]

I am looking for a way to obtain the class hierarchy of a program in MacPas mode (where there are 
no published properties). TObject has ClassParent, so a list of Class types would be sufficient, I 
think. I can't find however a routine in the RTL to obtain such a list.

Regards,
