  Modified:    lib/libF77  r_lg10.c
  Log:
  Use the C library version of log10() instead of the inaccurate formula
  log10(x) = log10e * log(x).  The formula would work if the RHS were
  evaluated in extended precision with an extended precision log().
  This actually happened with the i387 log() because it returns excess
  precision.
