GetTickCount on Win32 and rdtsc instruction on recent Intels.

Shame on me.. I was supposed some weeks ago to release such a routine (kinda promised it).. but didn't have yet the time for it. :(

Nope, I'm not the (c) of anything.. don't worry. You will find such routines written by others and kindly released by them in the public domain.

What I was mentioning is that I did promise to release one of mine, which was as much precise as possible (who knows me knows that I'm a bit perfectionist.. so some other "let's split the hair" coder like me may appreciate it :grin: ).

First I will release the next PROFILEr, then the maniacally precise CPUSPEED one.. when this inhumane load of job work is eased a bit on me.
