FWIW: I also double-checked the DWARF3 standard, and it says that the
value of this attribute is a flag, and following the hyperlinks in
the PDF, one gets to:

    flag
        A flag is represented as a single byte of data (DW_FORM_flag).
        If the flag has value zero, it indicates the absence of the
        attribute. If the flag has a non-zero value, it indicates the
        presence of the attribute.
