I also think GDB read_structure_type should cope with it right.

As GDB should not mind maybe we could propose DWARF extension
  DW_AT_specification -> DW_AT_specification or DW_AT_signature
in the paragraph:
  Structure, union and class entries containing the DW_AT_specification
  attribute do not need to duplicate information provided by the declaration
  entry referenced by the specification attribute. In particular, such entries
  do not need to contain an attribute for the name of the structure, class or
  union they represent if such information is already provided in the
  declaration.
