3.4.3. Block scope function declarations
Two extensions to block scope function declarations are supported:
a block-scope function declaration also declares
the function name at file scope
a block-scope function declaration can have static
storage class, thereby causing the resulting declaration to have
internal linkage by default.
void f1(void)
{
static void g(void); /* static function declared in local scope */
/* use of static keyword is illegal in strict ISO C */
}
void f2(void)
{
g(); /* uses previous local declaration */
}
static void g(int i)
{ } /* error - conflicts with previous declaration of g */
