Subject: [PATCH] examples: remove unnecessary include of <bits/pthreadtypes.h>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The <bits/*.h> header files are GNU libc specific, and should not be
used directly from application code. This one in particular is already
included by <pthread.h> on glibc.

Fixes build on musl.
