This fixes the following warning when building the docs (probably from
the commit for issue #14901):

"/Doc/faq/windows.rst:138: WARNING: undefined label: setting-envvars (if the
link has no caption the label must precede a section header)"

This adds to the work done for issue #15990 (i.e. f44b8d69e5fc and the
commits referenced there).
