More floating point digits?

I checked a 64-bit and 32-bit system for max_integer with the following results:
AMD Athlon 64 max_integer is 1152921504606846975 :)
Intel Pentium 3 max_integer is 268435455
 
However when I check the floating point representation I always get the same
16 meaningfull digits.  The maximum exponent was 307.
AMD Athlon 64: X is (1/3).  X = 0.33333333333333331 ;)
Intel Pentium 3: X is (1/3).  X = 0.33333333333333331
 
Is there a build option when increases the floating point precision or is this
representation part of gprolog 1.3.0.
