The build of this module fails with this error:

Changing the value of _XOPEN_SOURCE from 500 to 600 in Modules/_multiprocessing/multiprocessing.h fixes it.

I don't think you can blindly change that value of that definition. It will likely break the compilation of the module using Solaris Sun Studio while fixing compilation with gcc. The attached patch should do the correct thing in the presence of either toolchain.

Agreed, that is a better approach.
I have tested your patch successfully with gcc on Solaris 11.3.

_XOPEN_SOURCE is no longer defined in multiprocessing.h. Is there anything left to do here or can we close it as out of date?

I don't see anything further needed with this issue.  Closing it is fine with me.
