‘main’ is normally a non-static function ERROR

Question

There are two errors that show up: main.c:80: warning: ‘main’ is normally a non-static function main.c:88: error: expected declaration or statement at end of input and I cant't seem to find the problem... There number of curly braces is equal... What seems to be the problem?

   #include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
#include <getopt.h>

I've edited indentation for you. Do you see now that somewhere in parsing function you've missed one closing bracket?
