>Description:
When enable SEM option "Use POSIX semaphores (experimental)" in Makefile, python build is lack of SEM. For example when you want to use multirpocessing in python you get:

ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

This problem occured only in python26-2.6.2_3.

>How-To-Repeat:
Recompile python26-2.6.2_3 with SEM option. The SEM is still disabled.
>Fix:
The patch-setup.py overwrite correct changes made by extra-patch-setup.py patch.
You need change patch-setup.py as follows:
