  Log:
  Avoid an egcs pessimization for 64-bit signed division on i386's.
  Pre-2.8 versions of gcc generate a call to __divdi3() for all 64-bit
  signed divisions, but egcs optimizes them to a shift and fixup when
  the divisor is a constant power of 2.  Unfortunately, it generates
  a call to __cmpdi2() for the fixup, although all except possibly
  ancient versions of gcc and egcs do ordinary 64-bit comparisons
  inline.
