In C terms, argument types from an old-style declaration (in 
DECL_ARGUMENTS, not TYPE_ARG_TYPES) are not part of the function type.  I 
don't know enough about DWARF to judge if including them in the type in 
debug info nevertheless, but not marking that declaration with 
DW_AT_prototyped, would be incorrect or cause problems with DWARF 
consumers.
