Compiler Warning (level 4) C4205

nonstandard extension used : static function declaration in function scope

With Microsoft extensions (/Ze), static functions can be declared inside another function. The function is given global scope.

Example

// C4205.c
// compile with: /W4
void func1()
{
   static int func2();  // C4205
};

int main()
{
}

Such initializations are invalid under ANSI compatibility (/Za).
