--- Comment #1 from Mark Wielaard <mark at gcc dot gnu.org> ---
The DWARFv4 specification section 5.2 Unspecified Type Entries says "Some
languages have constructs in which a type may be left unspecified or the
absence of a type may be explicitly indicated. An unspecified (implicit,
unknown, ambiguous or nonexistent) type is represented by a debugging
information entry with the tag DW_TAG_unspecified_type. [...] For example, in C
and C++ the language implementation can provide an unspecified type entry with
the name “void” which can be referenced by the type attribute of pointer types
and typedef declarations for 'void'"
