It is known that on different Intel CPUs, glibc chooses at runtime 
different algorithms for certain floating-point operations (grep for 
HWCAP_I386_XMM, for example, which corresponds to SSE support). So here 
it may well be that this part of the Glibc testsuite in fact a testsuite 
for the CPU. For the meaningful comparison of the results, I ask both 
you and the original poster to post the contents of /proc/cpuinfo.
