That's a very indirect way of crashing because
ctypes.util.find_library('c') returned None, i.e. it did not

In more words, though, the important point is that you need to *not* sp

Agreed. Consistency
Hi,
Sorry for the series of mails. I just wanted to add that after
looking more at the code, it's fine if you implement major() and
minor() the same way as the other posix functions (see e.g. r79941

If you add tests in the sa
Re-hi,
I have opened an issue about the missing functions from the 'os' module:
https://codespeak.net/issue/pypy-dev/issue605
I will probably get around to implement a part of them in the next few
days. If you plan to do more than os.major() and os.minor(), let's
coordinate there.
A bientôt,
