I'm interested in what others think of the practice of declaring
function prototypes locally within a procedure.


local:

foo ()
{
 int bar (void);
 int x;

   x = bar ();

} 
--------------------------------------------------------------------

global:

int bar (void);

foo ()
{
 int x;

   x = bar ();
}


The advantage to the local declaration that I can see is that an
unintentional call to bar() will be flagged by the compiler. I prefer to
use the global declaration because if the definition of bar should
change, there's one place to change the prototype.

Any other opinions?

Thanks,
