Comment(by nickm):

 The errno stuff isn't quite the same on Windows.  There, you'll have to
 use the WSA* error codes listed in http://msdn.microsoft.com/en-
 us/library/ms740668(v=vs.85).aspx

 You can define a macro to make this easier:
 {{{
 #ifdef WINDOWS
 #define ERR(e) WSA##e
 #else
 #define ERR(e) e
 #endif
 }}}
 and then say
 {{{
  case ERR(EHOSTUNREACH): ...
 }}}
 and so on.

 Maybe the return values of socks5_handle_request want to turn into an
 enum?  Having magic meanings for -2...1 seems like the reason enum was
 invented.

 Instead of EVUTIL_SOCKET_ERROR(), you might want evutil_socket_geterror():
 it can be more accurate about connect failures on windows.

 Other than that, looks good!
