Why not take a look at allegro's routines? It has to detect Windows if you
intend to use the timer safely. Windows ver 4 is 95, 0x100 is NT, 3 is 3.x (you
get the idea).

Just a word of caution: Windows 95 (maybe NT) can disable the check your showed
above from MS-DOS prompt's advanced properties. I wish there were an easier way
of doing something like this, because it's not "good" for some programs and
Windows.
