From the original email:
Note this brings in the interface files for libcc1/G++ as well, which
we will be needing in GDB soon anyway. That commit renamed a method
in the C interface and that required a small update to GDB's compile/
code, which I've included that in this patch to keep the tree
building.
From the follow up email:

DWARFv5 defines and GCC5 may output two new DW_LANG constants for the
Fortran 2003 and Fortran 2008 standards. Recognize both in gold gdb-index
as unsupported.
For consistency also add the other new DWARF5/GCC5 language constants in
the elfcpp::DW_LANG enum to match include/dwarf2.h.
elfcpp/ChangeLog:
* dwarf.h (enum DW_LANG): Add DW_LANG_C_plus_plus_11,
DW_LANG_C11, DW_LANG_C_plus_plus_14, DW_LANG_Fortran03 and
DW_LANG_Fortran08 from ../include/dwarf2.h.
gold/ChangeLog:
* gdb-index.cc (Gdb_index_info_reader::visit_top_die): Recognize
DW_LANG_Fortran03 and DW_LANG_Fortran08.
Update DWARF enums from ../include/dwarf2.h.
* dwarf.h (enum DW_TAG): Add new DWARF-4 tags.
(enum DW_FORM): Add new DWARF-4 and Fission extensions.
(enum DW_AT): New enum.
(enum DW_LINE_EXTENDED_OPS): Add new DWARF-4 opcode.
(enum DW_ENCODING): Add new DWARF-4 encoding.
(enum DW_OP): Add new DWARF-4 opcodes.
(enum DW_CHILDREN): New enum.
(enum DW_LANG): New enum.
