GCC doesn't diagnose function-scope VM declarations of variables with external
or internal linkage. (VM declarations of function-local statics are OK.) Four
tests (all should be rejected unconditionally, none are even with -std=c99
-pedantic-errors):
extern int (*a)[];
void f(int b) { extern int (*a)[b]; }
static int (*a)[];
void f(int b) { extern int (*a)[b]; }
extern int (*a)[];
void f(int b) { typedef int (*T)[b]; extern T a; }
static int (*a)[];
void f(int b) { typedef int (*T)[b]; extern T a; }
