It seems strange that both the new and the old declarations are at the same
location...
Isn't input_location is a symbolic value standing for the location of
the decl argument that's being printed?
No, it typically points to the last token parsed. The reason your
diagnostics have the location of the decl arguments is because of the
'+' in the %q+#D format, which overrides the location given in the first
argument. So you could just as well use 0 instead of input_location, or
use 'error' rather than error_at.
