I am surprised that this works. Boost.Build appears to ignore the 
command line environment you launch it within, and so always chooses 
the default toolset for msvc-12.0, therefore producing binaries which 
ought to fail to launch on XP.

BTW, if you statically link your VS2012 executable as a DLL, and then 
use a loader shim on XP to load that DLL and call its entry point, 
you generally get away with it working just fine. In the end the 
VS2012 MSVCRT doesn't use that many Vista only kernel APIs yet.
