Absolutely, yes, I thought about that and just be done with it.

I wonder if that's the right compiler behavior though;
is it acceptable that the compiler cannot figure out that needle is always 
initialized before use when you have

switch (format) {
case 'c':
    needle = SOMETHING;
...
}

if (format != 'c') {
    needle = SOMETHING_ELSE;
}

actually_use(needle);

?
