Hello, OK, MMX is a special set of functions used for the pentium-pro and upwards (or was it already in pentium?). The most corresponding buzzword is 'single instruction, multiple data'. So you may add 4 16-bit integers at the same time, or multiply, or do other stuff. But, as a good guess, if you have nowhere something like #include "mmx.h" in your code, this shouldn't be a problem. It was just something I ran into when writing some code that used floating-point and MMX... For further information, you may look at: http://web.tiscali.it/tommesani/MMXPrimer.html Or a multitude of other web-pages that treat the subject.
