Comment (by bugzilla):

 Replying to [comment:21 teor]:
 > We can't make this change to the patch, because addr requires locally
 allocated storage, but ipv6_addr does not.
 N/A transforming ipv6_addr into the same type as addr? No problem.
 > This change may cause compiler warnings on some platforms due to casting
 the int return value to the fixed-width variable. The width of int is
 irrelevant when it's used as a boolean.
 It's a general suggestion for the entire project. Is {{{bool}}} prohibited
 in Tor?
