the program below should result in a warning that "j" might be used
uninitialized. If the "baz" call is replaced with an explicit assignment
to "j" a warning is generated as expected.

(stunning silence)
extern int bar (int);
extern void baz (int *);
int
foo (int i)
{
int j;
if (bar (i)) {
// These should do the same with respect to `j':
baz (&j);
// j = 1;
} else {
}
return j;
}
