Rule 18.8 and clarification of "use" of VLA types

[misra-c]

Rule 18.8 applies to uses of VLA types. The intention of the MISRA-C working group is that "uses" include the places where the type is "used".
e.g.

• Declaration of objects;
  typedef int32_t myVLA [x];

Code:

void foo(uint32_t sz,
         int32_t (*ary)[sz],   /* not compliant */
         int32_t val)
{
    (*ary)[0] = val;  /* not applicable to this rule */
}
