Empty case statements

[ignatirabo]

Hello, similarly to #528, PyCParser does not accept case statements that do not have statements while GCC does.

Example:

int main() {
  int i = 0;
  switch (i) {
    case 0:
      i = 1;
    case 1:
  }
  return i;
}

Is it possible for me to do a pull request with this feature?

Thank you in advance.
