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

meta information like what? I don't think it stores more variables used in class unless you used that 'virtual' shit which you should be staying away at the first place
