Visual Studio 2012 has switched the default to "/arch:SSE2", if we want
to support those old CPUs we have to use "-arch:SSE" (or even
"-arch:IA32", although i'd hope every CPU that can run WinXP supports SSE).

that's reasonably easy to do for our own code, but probably a bit more
effort for the bundled external libraries...
