Hello guys.
I'm newbie about the GCC compiler. Also, my english skill is poor, please
understand it.
Actually, When I compile using below command, my source are deleted. 
gcc -o mysource.c mysource
I know this command is wrong. but I think that this is a problem. because user
can make a mistake. Also user can't recover his source code everything. 
So, I think that If user input the like upper commend, we can change the
parameter order or backup the source file.
If you agree this situation, I'll try upload the patch.

Probably can be closed as a dup of PR36312 (which added "input file is the same
as output file").
