[Bug middle-end/24239] spurious warning about clobbered variables w.r.t. longjmp

Indeed, in gcc-4.0.1, the previous code chunk does not elicit a warning.
However, a slightly modified version still gets a warning (tested
on RHEL-4, with <gcc version 4.0.1 20050727 (Red Hat 4.0.1-4.EL4.2)>).

<c-code>
#include <setjmp.h>

extern int f(void);
extern int g(int);
extern jmp_buf jb;
extern int i;

int f(void)
{
  int j;

  if( i > 10 ) j = i;
  else j = i + 10;

  if( !setjmp(jb) ) {
    g(j);
  }
  else {
    j = -1;
  }

  return j;
}
</c-code>
