  24 # 1. access to class data members inside method scopes
  25 # 2. correct param types for methods in ptype.
  26 # 3. const and volatile methods
  27
  28 # (#0 and #1 above relate to an HP specific problem -- GDB must correctly
  29 # integrate FPARAM symbols in HP debug info into the local var list
  30 # for the function or method's block.)
