How about compiling this with -Wcast-align and looking for a warning message:

char *y;
typedef char __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) c;
c *z;
void foo(void)
{
        z = (c *) y;
}


I get a warning on IA64 but none on X86.  The warning is coming from
c-typeck.c.

x.c: In function 'foo':
x.c:6:13: warning: cast increases required alignment of target type
[-Wcast-align]
