* Dwarf: Hide the implicit pointer from a function-parameter which is
by reference, and dereference the (hidden) pointer in the DW_AT_location
block. This solves problems with function parameters defined as 'var'
Modified : /trunk/compiler/dbgdwarf.pas
But it seems that now, even in dwarf-3 objects are treated as pointer
again? (I can happily live with that. I just want to know)
