11# CAUTION: Do not use this makefile with gcc versions 2.7.2.2 and earlier.

13# NOTE:  When testing MMX performance on a multitasking system, make sure
14#        there are no floating-point programs (e.g., SETI@Home) running in
15#        the background!  Context switches between MMX and FPU are expensive.
