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