SetWindowTextW is a function that returns BOOL, instead of raising
exception. Secondly MultiByteToWideChar is again a function that returns
naturally not what you call it for. That has to be allocated first, of
unknown in advance length, of course, and then passed to
MultiByteToWideChar among other 6(!) parameters. So ugly prefix "+" does
not much help. And if we designed Win32Ada bindings from scratch it would
not be needed anyway.
