  Log:
  Since version 4.3, gcc changed its behaviour concerning the i386/amd64
  ABI and the direction flag, that is it now assumes that the direction
  flag is cleared at the entry of a function and it doesn't clear once
  more if needed. This new behaviour conforms to the i386/amd64 ABI.
  
  Modify the signal handler frame setup code to clear the DF {e,r}flags
  bit on the amd64/i386 for the signal handlers.
  
  jhb@ noted that it might break old apps if they assumed DF == 1 would be
  preserved in the signal handlers, but that such apps should be rare and
  that older versions of gcc would not generate such apps.
