Distutils currently can not handle a Posix platform that does not implement fork(). This patch retries with the _spawn_nt to use the spawn() methods if fork() is not implemented. A platform that does not implement fork() can provide spawn*() methods for python to use.
There are multiple degrees of Posix compliance. While X/Open documents the Posix requirements for implementing fork(), so far I have not found anything that requires that fork() be present. Configure tests for c-python also test for the presence of fork(). OpenVMS complies with many Posix standards, but does not implement fork().
Note that Python directly supports Unixes which supply fork() and Microsoft Windows that supplies spawn*() methods. So as long as a platform supports either the fork() or the the Microsoft Windows spawn() methods, there should not be barriers implementing Python on it even if that platform is not directly supported.
Distutils is now deprecated (see PEP 632) and all tagged issues are being closed. From now until removal, only release blocking issues will be considered for distutils. If this issue does not relate to distutils, please remove the component and reopen it. If you believe it still requires a fix, most likely the issue should be re-reported at https://github.com/pypa/setuptools
