  Modified files:
    sys/conf             kern.pre.mk 
  Log:
  While we're building kernels -g (ie, makeoptions DEBUG=-g), use -O as it
  provides truer debugger stack traces.  For those that want to stick with
  -O2 kernel builds, one should probably add -fno-optimize-sibling-calls
  so that each stack frame as a frame pointer.
  It is semi-promissed by the Release Engineers that when RELENG_6 is
  created we go back to -O2.
