So we should do our cpucheck first and later compare the results to the ones
from IsProcessorFeaturePresent? What about
gCpuCaps.hasMMX2
gCpuCaps.hasSSE2
gCpuCaps.has3DNowExt
are they used in the mplayer codebase?
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/bas
e/isprocessorfeaturepresent.asp
doesn't list them
