David Schultz 6955d806c0 Remove some kludges designed to ensure that the compiler didn't round
constants the wrong way on the VAX.  Instead, use C99 hexadecimal
floating-point constants, which are guaranteed to be exact on binary
IEEE machines.  (The correct hexadecimal values were already provided
in the source, but not used.)  Also, convert the constants to
lowercase to work around a gcc bug that wasn't fixed until gcc 3.4.0.
