Hi, all.
The error messages as below -
[...]

It seems caused by the patch for dns-sd.c -
[...]
    172 #ifdef __linux__
    173         static const char kFilePathSep = '/';
    174         static size_t _sa_len(const struct sockaddr *addr)
[...]

BTW, why the patch name not to follow the patch-xx rule?
