To the best of my knowledge, `uclock' works on Windows 9X, although I
never tested it on Windows 98 SE specifically.  Some of the
improvements that went into DJGPP v2.03 especially targeted Windows 9X
idiosyncrasies related to reprogramming the system timer.

`clock' should work reliably on Windows, but it has much lower
resolution.

`usleep' uses `clock' internally, so it only has 55-msec granularity.
I suggest to use `usleep', unless you find problems with it (in which
case please report them here).
