It's probably because the field "rev" of struct path_rev_t is declared
as being "const". Because of this, it's not allowed to assign
anything to a variable of this struct type. However, according to
6.7.8:13 these declarations have the semantics of an initial value
and not an assignment, so unless I'm misinterpreting the standard
it should be allowed and there's a bug in the compiler that it treats
it as an assignment.
