3.6.8 Integral type extensions
In an integral constant expression, an integral constant can be cast to a pointer type and
then back to an integral type.
3.6.9 Label definitions
In Standard C and Standard C++, a statement must follow a label definition. In C and
C++, a label definition can be followed immediately by a right brace.
Errors
The compiler generates a warning if a label definition is followed immediately by a
right brace.
Example
void foo(char *p)
{
if (p)
{
/* ... */
label:
}
}

Non static local variables of an enclosing function can be referenced in a non evaluated
expression, for example, a sizeof expression inside a local class. A warning is issued.
