Therefore I wrote "can live" and not "should use". I think there are
cases, where it makes sense, but they are rather the exception than the
rule.

Well, for the first one: To make sure that the conversion actually works;

for the second one: To make sure that the two "u" don't clash, which is
detected at link time
000000000040067e T __m__u
0000000000400678 T __n__u

Especially for the first one, I'm not sure whether we could not manage
to break it.
The second one is fairly unlikely, but doing not only compiling but also
linking does not cost much time.
