[New-bugs-announce] [issue35903] Build of posixshmem.c should probe for required OS functions

[Neil Schemenauer]

New submission from Neil Schemenauer <nas-python at arctrix.com>:

The logic in setup.py that determines if _multiprocessing/posixshmem.c should get built is not very robust.  I think it is better to use autoconfig to probe for the required functions and libraries.  My autoconfig brain cells are a bit fuzzy but I think my patch is correct.

I look for shm_open and shm_unlink.  I also check if librt is required for these functions.
