extern question

Is the following acceptable C code:
extern int foo();
bar()
{
int (*bla)() = foo; /* CASE 1 */
foo(); /* CASE 2 */
}
static int
foo()
{
...
}
In other words, should extern be interpreted as "possible forward
reference" (the way I'm using it), or "externally defined symbol"? All
the compilers I have used handle case 2 ok, but one couldn't deal with
case 1. Shouldn't they both work the same?
>From an aesthetic viewpoint, I like to use extern anywhere I declare
something but don't define it. I think writing
int foo();
for static functions is not as clear.
