I would prefer to see the build assert in the else block.

PEP 7 now requires {...} around if blocks.

I think that compilers are smart enough to computes the check at compile time, and so remove the dead code. I mean, I like your change. I just ask minor changes.

Shouldn't this get backported to 3.6 after the backport #584 broke 3.6 so that 3.6.2 unfortunately does not compile on Android?

My understanding is that, Android not being a supported platform, changes that are specific to Android are only made to the master branch. I may be wrong.

My fault then. Thought 3.6 was targeting Android but that's not actually stated anywhere (There are some Android specific things in the 3.6 changelog though).

IMHO this change is simple enough to justify a backport: I created the PR #3102. While 3.6 doesn't fully support Android, we are doing our best support Android and any kind of help is welcome!

Encountered this issue while compiling PyQt5 for RaspberryPi/ARM with Python 3.6.2. Copying posixmodule.c from 3.6 branch fixed the posixmodule.c:1935:5: error: array size is negative error.

e.g.:

wget https://raw.githubusercontent.com/python/cpython/ffbb6f7334ccf54f09dcc9e760766d861928f13e/Modules/posixmodule.c
mv posixmodule.c Modules/

@thijstriemstra: Cool! Good to know. I hope that slowly, we will get a release with a correct Android support.

Thanks @xdegaye for the long term effort on supporting Android!
