+<p>Each of the various packages,
+which are distributed by MinGW.org,
+is governed by its own individual copyright and licensing terms.
+In summary, the applicable terms for the web‑site content,
+and for the most commonly deployed packages,
+are as follows:—
+</p>
+<h3>MinGW.org Web‑Site Content</h3>
+<p>Publication of the content of this MinGW.org web‑site is
+subject to the terms of
+<a href="#"
+onclick="load_page_content('fdl.html','The MinGW Free Documentation Licence')"
+>this MinGW specific adaptation</a>
+of the
+<a rel="noopener noreferrer" target="_blank"
+href="https://www.freebsd.org/copyright/freebsd-doc-license.html"
+>FreeBSD Documentation Licence</a>.
+</p>
+<h3>MinGW.org Windows System Libraries (WSL)</h3>
+<p>Not to be confused with
+Microsoft’s “Windows Subsystem for Linux”,
+(MinGW.org’s adoption of the “WSL” acronym
+preceded Microsoft’s by several years),
+the “MinGW.org Windows System Libraries” comprise:—
+</p>
+<ul>
+<li>the “MinGW C‑Runtime Library” (mingwrt), and</li>
+<li>the “MinGW Windows API” (w32api).</li>
+</ul>
+<p>Prior to version 4.0,
+these constituents of MinGW.org WSL were released independently,
+with no synchronization of their version numbers.
+There is a commonly held misconception,
+that both of these constituent packages
+were released into the public domain,
+and thus, were exempt from licensing and copyright considerations.
+However,
+while it is true that all
+<em>direct</em> contributors to MinGW agreed to waive copyright,
+it is <em>not</em>,
+and <em>never has been</em> true
+that the entire code base is exempt from copyright;
+in fact,
+substantial portions of the code base have been acquired from third parties,
+who retain copyright,
+and have granted permission to redistribute under licences such as BSD,
+or MIT/X11, so while parts of the code base <em>may</em> be public domain,
+the work as a whole must be considered to be licensed under
+a hybrid collection of BSD, MIT/X11,
+and a few other compatible (generally very permissive) licences.
+</p>
+<p>From version 4.0 onwards,
+the two constituents of the “MinGW.org Windows System Libraries”
+have been published as an integrated package set;
+(version 4.x blurred the distinction between the two constituents;
+version 5.x reinstated it,
+but the two constituents are <em>always</em> released concurrently,
+with <em>strictly</em> synchronized version numbers).
+Additionally,
+from the release of version 4.0,
+and on account of the inadmissibility of the very concept of public domain,
+in certain legal jurisdictions,
+the entire “MinGW.org Windows System Libraries” suite
+has been published under the terms of
+<a rel="noopener noreferrer" target="_blank"
+href="http://git.osdn.net/view?p=mingw/mingw-org-wsl.git;a=blob;f=LICENSE;
+h=d5640dc6377de4b4e9af1a472b0be5999b885a71;hb=HEAD"
+>the MIT/X11 Licence</a>,
+(except in the case of those elements of the code base to which
+some alternative <em>explicit</em> licence was already applicable;
+such elements retain their original licensing terms).
+</p>
+<h3>MinGW.org WSL Code Profiling Extensions</h3>
+<p>The code profiling extensions,
+which are included within
+the “MinGW.org Windows System Libraries” distribution,
+are licensed under the terms of the
+<a rel="noopener noreferrer" target="_blank"
+ href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
+>GNU General Public Licence (GPL), Version‑2</a>.
+If you use these profiling extensions within your code,
+then your application becomes subject to the terms of the GPL‑v2.
+</p>
+<h3>MinGW Distributions of GNU Packages</h3>
+<p>Other than the
+“MinGW.org Windows System Libraries”,
+the principal packages which comprise the MinGW distribution,
+including the “GNU Compiler Collection (GCC)”,
+the “GNU Binary Utilities (binutils)”,
+the “GNU Debugger (GDB)”,
+and “GNU Make”,
+are derived from upstream GNU packages;
+as such, they are distributed under the terms of the
+<a rel="noopener noreferrer" target="_blank"
+ href="http://www.gnu.org/licenses/licenses.html#GPL"
+>GNU General Public Licence</a>;
+(in the case of more recent releases,
+this will normally be GPL‑v3;
+earlier releases may often still be under GPL‑v2).
