Update of /usr/src/master/nhc/src/prelude/Prelude
In directory hinken:/tmp/cvs-serv18228

Modified Files:
	RealFloat_Double.hs RealFloat_Float.hs 
Log Message:
Remove errors about unimplemented float/double functions.  For isNaN
and isInfinite at type Double, there are C library implementations.
For isDenormalised, isIEEE, isNegativeZero at both types (and isNaN,
isInfinite at type Float), simply return False like Hugs and Ghc do.
