[Bug c/25733] missed diagnostic about assignment used as truth value.

I am not saying that the warning is not useful. I am saying that the current
behaviour of not warning if there are parenthesis is not ideal. 

So either:

if ((bool) a = 0)

or 

if ( (a=0) != 0)

seem much better choices for avoiding warning.
