To get rid of your error messages what you need to do is:
	gcc -o exe_name -O2 obj1.o obj2.o
NOT
	gcc -o -O2 exe_name obj1.o obj2.o

But, that will not do any optimization, because that is 
linking which won't do any real optimization. 
What you need to do is change your compile line
that creates the .o files to look like
	gcc -c -O2 obj1.c

Good luck!
