Unnecessary parser warnings can't be disabled

I haven't found a way to disable the built-in parser warnings. Really the only one that really annoys me is the "unnecessary semicolon after block" warning, which is itself the ultimate unnecessary warning. I'm using a unit test framework that uses function-style macros with blocks, so I get this warning on almost every test line. It seems like it's slowing down the gui, as well as annoying the heck out of me.
