If you want optimization hints particular to the code you wrote (not just
the problem that your code solves), we would need to see your code.

Here it is, the full source codes:

Be sure to read the enclosed copyright notice, by the way.

The code contains parts specifically made for the Pentium
4 and compatible processors, by the way.

After removing the useless header definition <conio.h> in pib26.h, I
was able to compile but not link:

I guess that you used some custom time library. Might be nice to say
what it was in a readme file or something like that.
