\A{thirdparty} Third-party software licences

\# This file should contain the copyright notices for third-party code
included in the Emscripten builds of Puzzles.  To get a list of
relevant source files, you can build Puzzles with "-gsource-map" and
then do something like:

\# jq -r '.sources[]' *.map | sort -u

\# This file is based on a build of Git commit
2e48ce132e011e83517a9fc4905edcc8f9a5ef58 using Emscripten 3.1.35

\# system/lib/compiler-rt/lib/builtins/*
\# upstream/lib/clang/17/include/tgmath.h

\# These are under the Apache Licence v2.0 with LLVM Exceptions.  The
LLVM Exceptions allow us not to mention them in binary distributions.

\# system/lib/dlmalloc.c

\# dlmalloc is in the public domain and so needs no acknowledgement.

The JavaScript and KaiOS versions of Puzzles incorporate some third
party software.  Most of it is licensed under the \i{MIT licence} (see
\k{licence}) and requires the following \i{copyright} notices:
