Presumably because you don't have a DWARF language code for D.  What's
it labelling the language as in the DW_TAG_compile_unit DIE?

You can define one temporarily for now, but you'll need to request from
the DWARF working group eventually.

Perhaps.  Are there multiple implementations of D?  How inconsistent
are they in ways that would affect GDB?

If you want to do this, you will eventually need a GDB copyright
assignment with the FSF.
