At the moment both os.stat() and stat_result are implemented in C, and I
have to keep the option open that the work I do may need to be done in C
as well. I've written C extensions to Python before that reference types
defined in plain .py files, but I'm not sure if that's idiomatic or
permitted in CPython, so I have to keep my options open.

Technically, the definitions of the S_IS* macros in the C header files
are the only authoritative way to interpret st_mode, the Python stat
module is not a normative part of POSIX at all ;-)

If I'm forced to implement in C, I'll use the POSIX libc macros. If I
implement in python, I'll use the existing stat module, and benefit from
your patch when it is accepted.
