  Modified files:
    sys/boot/i386/boot2  Makefile 
  Log:
  Add -fdata-sections, which is a new GCC 2.95 optimization.  Remove
  -fschedule-insns as it wasn't such a big win with 2.95 after all.
  
  Add the *BIG* win "-mpreferred-stack-boundary=2" optimiztion submitted by
  Dima.  GCC 2.95 ensures the stack frame is always properly [opitimally]
  aligned by surrounding every function call by code simular to
  "addl $-12, %esp" / "addl $12, %esp".  Here we need the reduction in space,
  with speed not an issue.
