After checking out gcc version 4.10 the first test already
revealed a flaw:

My test-program reported that it was running about
5 times as fast as compared to its 4.01 compiled version.

As I don't believe in miracles, I suspect that a bug has
crawled into the clock() function and/or the CLOCKS_PER_SEC
definition.

I have further noticed a 6% jitter in the values which
are returned by clock() after about 5 seconds. But this is
not necessarily related to the above mentioned problem.
