There is code in error.c:type_to_string to print "{aka ". It does some tricks
to avoid printing aka when there are no typedefs. Perhaps args_to_string()
should call type_to_string() instead of calling dump_type directly. With that,
it prints:
test.cc:6:6: error: call of overloaded ‘f(NT& {aka unsigned int&})’ is
ambiguous
I am not sure if that is clearer or not. But it avoids the repetition.
