Good point. There is a proposal to add DW_LANG_C_plus_plus_03 (0x17) and
DW_LANG_C_plus_plus_11 (0x18)
http://dwarfstd.org/ShowIssue.php?issue=120628.1
But no DW_LANG_C_plus_plus_14 yet. Probably because C++14 only got
approved last August. Although it has been too late to submit new
proposals for DWARFv5 since a couple of months now I did submit one
anyway. Hopefully we can still sneak it in before there is a first draft
of DWARFv5 out. http://article.gmane.org/gmane.comp.standards.dwarf/218

Cheers,

Mark
