This actually is a rather common thing. Declare function pointers 
for the newer API functions. At run time, use LoadLibrary and 
GetProc to load them from the system DLLs. If GetProc can't find 
the symbols, you know that this version of Windows doesn't 
support them, so you fall back to the older stuff.
