ChangeLog:
* dwarf2read.c (dwarf2_name): Work around GCC bugzilla debug/41828 by
ignoring spurious DW_AT_name attributes for unnamed structs or unions.
* completer.c (add_struct_fields): Fix inverted logic.
testsuite/ChangeLog:
* gdb.cp/inherit.exp (test_ptype_si): XFAIL test for GCC versions
that do not provide the tagless_struct type name at all.
(test_print_anon_union): Do not check value of uninitialized
union member. Do not use cp_test_ptype_class, so we can accept
"long" as well as "long int".
