Subject: [PATCH 2/2] Prevent infinite recursion with pip wheel with $TMPDIR in
$PWD
During a build of extension module within `pip wheel` the source directory is
recursively copied in a temporary directory.
See https://github.com/pypa/pip/issues/7555
When the temporary directory is inside the source directory
(for example by setting `TMPDIR=$PWD/tmp`) this caused an infinite recursion
that ended in:
[Errno 36] File name too long
We prevent that buy never copying the target to the target in _copy_source_tree.
Fixes https://github.com/pypa/pip/issues/7872
Avoid a test dependency on a C compiler, skip the test on Windows
