OK, so just to be clear this isn't actually used as a linkage_name by
GDB then? And the name `t' is kind of arbitrary? The "rule" for the
extension is that there should be an identifier in DW_AT_linkage_name
for an anonymous structure_type (which doesn't have DW_AT_name set)?

I am just wondering whether you have thought about submitting it as an
official DWARF extension.

Thanks,

Mark
