The error "struct timezone" is because mingw follows the POSIX specification and defines "struct timezone".
The author defines "struct timezone" because "struct timezone" is not defined under Windows.
To solve this error, you just need to comment "struct timezone" in "gettimeofday.h".
The same is true for the errors about "inet_pton" and "inet_ntop", you need to comment them in the HEAER file.
The reason for this may be that these functions were not defined under previous mingw.
