I've used both styles in different languages over the years. I don't
know that one is a clearly better way, notwithstanding what various
theorists might say.
Note that in C89 it's fantastically easy to put the declaration as close
as you like to the first use of a variable. All it takes is a pair of
braces enclosing the variable scope.
Even if we were to relax our rules on this, making wholesale changes
along these lines and even more backpatching them seem out of the question.
