 Obfsproxy is doing the C-OO structures trick, and is using sockaddr/
 sockaddr_in/ sockaddr_storage in normal ways. This will make GCC's strict
 alias checking generate incorrect code under annoying circumstances.  When
 building with GCC, obfsproxy should make sure that the -fno-strict-
 aliasing flag is passed to the compiler, or expect a big fun surprise.
