‘main’ is normally a non-static function ERROR

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?

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