The potential for this problem arising was extremely high on Alpine Linux,
but seem to be very rare on a full Linux of macOS distribution where glibc
was being used.

+* Include a potential workaround so that virtual environment work on Windows.
+
+ Use of virtual environments in embedded systems on Windows has been broken
+ ever since ``python -m venv`` was introduced.
+
+ Initially ``virtualenv`` was not affected, although when it changed to
+ use the new style Python virtual environment layout the same as
+ ``python -m venv`` it also broke. This was with the introduction of about
+ ``virtualenv`` version 20.0.0.
+
+ The underlying cause is lack of support for using virtual environments in
+ CPython for the new style virtual environments. The bug has existed in
+ CPython since back in 2014 and has not been fixed. For details of the
+ issue see https://bugs.python.org/issue22213.
+
+ For non Window systems a workaround had been used to resolve the problem,
+ but the same workaround has never worked on Windows. The change in this
+ version tries a different workaround for Windows environments.
