Standardized predefined CPP symbols, down with folklore

I think that, once upon a time, the preprocessor *did* #define unix unix.
But at the point that cpp began accepting #if in addition to #ifdef,
the default value of defined parameters changed from themselves to 1.
You can use "1" in both #if and #ifdef.
