warnings?</para></question>
+ <answer>
+ <para>Older Cygwin releases asked users to report problems to the mailing
+ list with the message:</para>
+ <screen>
+ find_fast_cwd: WARNING: Couldn't compute FAST_CWD pointer. Please report
+ this problem to the public mailing list <ulink
url="mailto:cyg...@cygwin.com";>cyg...@cygwin.com</ulink></screen>
+ <para>Recent Cygwin releases changed this to the message:</para>
+ <screen>
+ This typically occurs if you're using an older Cygwin version on a
newer Windows.
+ Please update to the latest available Cygwin version from <ulink
url="https://cygwin.com/";>https://cygwin.com/</ulink>.
+ If the problem persists, please see <ulink
url="https://cygwin.com/problems.html";>https://cygwin.com/problems.html</ulink>.</screen>
+ <para>This is not serious, just a warning that Cygwin may not always be
+ able to exactly emulate all aspects of Unix current directory handling
+ under your Windows release.</para>
+ <para>Unfortunately some projects and products still distribute older
+ Cygwin releases which may not fully support newer Windows releases,
+ instead of installing the current release from the Cygwin project.
+ They also may not provide any obvious way to keep the Cygwin packages
+ their application uses up to date with fixes for security issues and
+ upgrades.</para>
+ <para>The solution is simply downloading and running Cygwin Setup,
+ following the instructions in the Internet Setup section of
+ <ulink
url="https://cygwin.com/cygwin-ug-net/setup-net.html#internet-setup";>
+ Setting Up Cygwin</ulink> in the Cygwin User's Guide.</para>
+ <para>Please exit from all applications before running Cygwin Setup.
+ When running Setup, you should not change most of the values presented,
+ just select the <literal>Next</literal> button in most cases, as you
+ already have a Cygwin release installed, and only want to upgrade your
+ current installation.
+ You should make your own selection if the internet connection to your
+ system requires a proxy; and you must always pick an up to date Cygwin
+ download (mirror) site, preferably the site nearest to your system for
+ faster downloads, as shown, with more details to help you choose, on the
+ <ulink url="https://cygwin.com/mirrors.html";>
+ Mirror Sites</ulink> web page.</para>
+ <para>Cygwin Setup will download and apply upgrades to all packages
+ required for Cygwin itself and installed applications.
+ Any problems with applying updates, or the application after updates,
+ should be reported to the project or product supplier for remedial
+ action.</para>
+ <para>As Cygwin is a volunteer project, unable to provide support for older
+ releases installed by projects or products, it would be helpful to let
+ other users know what project or product you installed, in a quick
+ <ulink
