    src/compiler98       GcodeLow.hs Prim.hs PrimCode.hs 
  Log:
  The default definition of (**) in class Floating loses precision.
  In particular, many calculations incorrectly have result NaN.
  The fix is to use the C library function pow() instead, and hook
  it into nhc98 as a new bytecode instruction.
