  27 # 1. access to class data members inside method scopes
  28 # 2. correct param types for methods in ptype.
  29 # 3. const and volatile methods
  30
  31 # (#0 and #1 above relate to an HP specific problem -- GDB must correctly
  32 # integrate FPARAM symbols in HP debug info into the local var list
  33 # for the function or method's block.)
