natDouble.java (doubleToLongBits): ensure that all NaNs are always converted to the same long value.
1999-04-14 Andrew Haley <aph@cygnus.com>
* java/lang/natDouble.java (doubleToLongBits): ensure that all
NaNs are always converted to the same long value.
* java/lang/natFloat.java (floatToIntBits): ditto, but for float
converted to int.
