But is there any real reason for the
#ifndef __SSE__
# error "SSE instruction set not enabled"

Maybe it could only be a warning or something? I think there are many
legitimate uses for SSE intrinsics in non-pentium3-specific code. Also,
I see no reason to force the move of intrinsics to separate files.
