[New-bugs-announce] [issue12826] module _socket failed to build on OpenBSD

[Remi Pointel]

New submission from Remi Pointel <python at xiri.fr>:

Hello,
I try to build Python 3.3 on OpenBSD, and it failed to build these modules: _socket (so _ssl too).

Errors are:

*** WARNING: renaming "_ssl" since importing it failed: No module named '_socket'

If I add a #include <sys/uio.h>, these 2 modules correcly build.

Attached file are:
-the diff
-the details of errors.

Thanks,
Remi.
