Yes, I know the difference between 'const char *' and 'char *' ;-)

The type cast actually is about 6 lines before the call to initPattern()
while the lines in between are completely unrelated to both.

Besides that, WHY then did it compile cleanly and not complain while
initPattern() was a static function "inside" the Foobar.m class file?

It just doesn't make sense to suddenly dump a warning, just because the
function now is "external".
