I may be wrong (parsing this stuff is worse for humans than
computers), but that doesn't declare msg as a const pointer. It makes
it a pointer to a const struct, and you don't want that.
It does indeed make it a pointer to const struct; that _is_ what is
desired. It is, basically, a function that cannot modify the object
its argument points to; this may permit a compiler to perform extra
optimizations.
This is a known bug in Saber.
