[Bug math/5547] New: lrint gives wrong result for ia64 and alpha -mieee

["bonzini at gnu dot org" <sourceware-bugzilla at sourceware dot org>]

Reproducer:

#define _GNU_SOURCE 1
#include <math.h>

int main()
{
  double d = 14988885582133630.0;
  printf ("%.18g\n", d);
  long int l = lrint (d);
  printf ("%ld\n", l);
  printf ("%ld\n", (long int) d);
}

Output on ia64

14988885582133630
14988881287166334
14988885582133630

On alpha a user of mine got the same error with -mieee, but I don't have a
machine to run the reproducer.
