Yea, but the implementation around TEMPLATE_DECLs is to skip anything 
that isn't a FUNCTION_DECL.

I can't find anything in dbxout.c which references language specific 
nodes, so I'm hesitant to add them, even in something as rarely used as 
dbxout.c.

Can we take inspiration from dwarf2out.c here?

See is_ccx_auto and how it gets used in the type code.
