It really really really won't. "test" is an internal bash call, not a 
seperate program, so running it is near nothing, and the 'gcc' calls are 
like 99.9% of the time anyway. You're basically saving an "strcmp"...

I'm a bit more curious if this doesn't break any functionality, that is, 
will not running these tests actually give some wrong results?.. If it 
does, then it's a problem, and if it doesn't, then why do we run the tests 
at all?...
