It's because the function returns a 'const <some_struct>'. If you change the
return type to '<some_struct>', the warning goes away.
Remembering that the return value of a function, in C, can be copied anyway
before it's assigned to its destination, the 'const' cannot prevent this
copying. So it is redundant.
