set_ld.c: replaced a struct by a union. The struct was triggering the

following warning with GCC 4.4:
  dereferencing type-punned pointer will break strict-aliasing rules
(possibly due to possible memory alignment problems). The old code
looked strange anyway and unions are exactly for such kind of things.
