For example... (Just the other day I was just reviewing/comparing Linux vs.
Windows nodes, what was _actually_ defined in runtime values versus what is
mentioned in the constants source)

You see a whole bunch of S_* constants not defined under Windows. And
fewer O_* constants under Windows. And for the same O_* constant names,
different values, like O_CREAT is either 0x0040 or 0x0100
So a question is - after which runtime, Windows, Linux, BSD, would you
model your available names and then their values?
