Wouldn't be that a good idea to allow for command line switch to turn on/=
off=20
particular CPUID flags? This would allow not only to work around missing =
SSE=20
instructions, but also allow to effectively check/debug executables with=20
variant code depending on presence of various CPU features (some performa=
nce=20
oriented apps do that; also ICC above 6.0 or 7.0 does that stuff=20
automatically).
