well, gcc does not "recover", we _gave_ it the format string as a
constant, and do so in 99.9% of the cases. It is a totally
well-specified thing.
so yes, this warning is bogus.
You are right that passing in a non-constant string to printf is
inherently dangerous though, and i'd suggest we warn about _that_ very
prominently.
but the constant noise from gcc about printf formats, where the
conversion is very clear and could be done implicitly, only hinders us
and only teaches people to _ignore_ gcc warnings - which is actually
very dangerous.
the only warning from gcc in this area should be where the format
results in information _loss_ (i.e. the format has a narrower type than
we pass into it) - there a warning is very much needed - and the
programmer should then fix the bug or add a cast.
