+slash, rather than falling back to the parent directory's metadata. This
+implicitly affected :func:`os.path.exists` and :func:`os.path.isdir`.

+Fix check for macOS SDK paths when building Python. Narrow search to match
+contents of SDKs, namely only files in ``/System/Library``,
+``/System/IOSSupport``, and ``/usr`` other than ``/usr/local``. Previously,
+anything under ``/System`` was assumed to be in an SDK which causes problems
+with the new file system layout in 10.15+ where user file systems may appear
+to be mounted under ``/System``. Paths in ``/Library`` were also
+incorrectly treated as SDK locations.
