Floating point problem on glibc-2.1.1

Package: libc6
Version: 2.1.1-1

We discover a floating point problem on glibc-2.1.1:

#include <math.h>
#include <stdio.h>

    printf("%d\n", (int)(log(8.0)/log(2.0)));

When compile this simple program with command:

	cc file.c -lm

and run it, the output is "2", but not "3"; while on other plateforms,
say, Solaries-2.5.1, the output is "3".

This problem also exists in glibc-2.0.7.

Best Regards,
