Maybe, but unless _S_IREAD and _S_IWRITE are defined as 0400 and 0200,
the code would have been doing the wrong thing altogether.

I'm not sure why you think the group/other macros couldn't be #define'd
as 0? But in any case there's still the question of where S_IRWXU is
coming from, since it clearly does work in several places.
