That's the key to it: most times.  Granted, without -Wall (or any other 
options that tweaks the default warning level) we can be very sure that 
the warning is the result of a mistake by the developer.  But with 
-Wall, many warnings are totally not interesting ("unused parameter") 
and some even try to outsmart the programmer even though he/she knows 
better ("taking address of variable declared register").  In that last 
example, fixing it would even be wrong when you consider the optimizer 
and the fuzzy meaning of "register" which the compiler is totally free 
to ignore.
