Analyzing ReactOS's code

I will only cite the following piece of code for dessert:

    #define SWAP(a,b,c)  c = a;\
                         a = b;\
                         a = c

Wow, so now /pork/ has degenerated to the point of discussing shit that was covered in the C++ FAQ twenty years ago.  I guess it really is over.
