Well, to my knowledge latest Visual Studio and MS Office don't support
XP (as the hosting OS). As well as recent games and some other
applications I happen to interact with. And the site you referred to
shows the decline.

Also note that the change is made to trunk and at best will be
released with 1.56 (i.e. sometime next year).

I'm not familiar with the testing scripts but yes,
"define=_WIN32_WINNT=0x0501" would be the option for bjam.
