Uemis patches

[Dirk Hohndel]

Hi Guido,

I did some minor changes (commit messages plus a small convention issue...
you need the (void)f() cast if you call a function that returns a value
and you then ignore it. But your new helper in patch 4 is of type void, so
you don't need to cast to (void).

Pushed.

/D
