Standard clock() measures CPU time, while Windows / MS DOS clock() measures
elapsed time. Most of us could use the old boost timer otherwise.

Moreover, Windows 95/98/ME did not provide alternative API to measure CPU
time. NT based Windows became dominant only recently; otherwise the problem
would be fixed long ago.
