There has been massive changes to C++ over the intervening years (and also changes to c). I strongly suggest you consider using this latest version.

I'm using it as a command-line compiler, so I don't need the rest of the IDE for most of what I'm using it for. That old version of MSVC++ is command-line only, so it doesn't require the large amount of harddrive space that newer versions of MSVC++ require.

Still your comment doesn't answer my question. My question is simply this:
What is the earliest known version of MSVC++ that truly inserts intrinsic CPU/FPU instructions into the compiled code when use of intrinsic instructions is requested by the command line /Oi switch?
