    sys/boot/i386/boot2  Makefile 
  Log:
  GCC3.4's (default) unit-at-a-time optimization is incompatible with -mrtd.
  Bad code (missing stack pops) will be produced.  See the assembly generated
  for 'xputc' with -mrtd and unit-at-a-time enabled for an example of this.
  
  GCC3.4's unit-at-a-time seems to cause other problems as well, specifically
  in boot2, as yet not tracked down, so disable unit-at-a-time optimizations
  for the boot code if the compiler is not GCC2.
