Is there a reason you need to run all unittests every time you 
want to run the program?

I personally compile with -unittest to make sure all my unittests 
pass, then recompile without the -unittest flag if I actually 
want to run the program.  This way, time isn't wasted running 
unittests every time the program is run.
