/* If we are reading an enum from a .debug_types unit, and the enum
is a declaration, and the enum is not the signatured type in the
unit, then we do not want to add a symbol for it. Adding a
symbol would in some cases obscure the true definition of the
enum, giving users an incomplete type when the definition is
actually available. Note that we do not want to do this for all
enums which are just declarations, because C++0x allows forward
enum declarations. */
