CWEAVE didn't check for malicious user input like @*1234567890123456,
which certainly would over-/underflow INT_MAX. :o)

Apple's XCode 14 (Clang) issues deprecation warnings for the 'sprintf'
system function (from <stdio.h>) when used with C++. As I am compiling
CWEB as C++ code (locally, not in TeX Live), I became aware of this
possible future issue.
While common.w diligently checks user-provided file names for possible
buffer overflows before invoking 'sprintf' (sections 77--79), I replace
the uses of 'sprintf' in ctangle.w and cweave.w and cweav-twill.ch with
the safer 'snprintf' alternative.

TODO: Study the application of 'ctwill-twinx' and create a general index
for COMMON and CTWILL.

This release is almost the same as CWEB 4.3 of 2021-04-16, but
* it fixes the indexing bug in CWEAVE/CTWILL that got retracted
* it extracts and collects all additions made in CTWILL, so that the
section numbers of CWEAVE are retained up to §272 and new material is
described in the (first) appendix, including the CTWILL user manual
* it provides fully revised and (hopefully) corrected mini-indexes for
CTWILL, if it is processed by itself (to be published in package
'knuth-pdf' on CTAN)

This reverts commit 3ccac2a7d0f4a19dde861c6f4c178e853d90f0cc.
CWEB 4.3 is seriously broken.

This release introduces new features to CWEB 4:
* Former option '-t' is now called '-c'.
- New option '-t' for CWEAVE when dealing with 'typename' in
C++ templates.
- New option '-k' for CTANGLE to keep '-separators in numeric
literals.
* Support for "variadic macros" along "variadic functions".
* @d is printed similar to #define (and vice versa):
- '#' is no longer printed in boldface.
- Spacing is similar in most cases.
* Support for extended C99/C++ numeric literals:
- hexadecimal, octal, and -- new! -- binary numbers.
- NOTE: 'cwebmac.tex 4.3' is NOT compatible with CWEAVE 4.2 and older
and vice versa.
* Long parameter lists in ANSI function definitions are indented similar
to old-style function parameters.
- Option '-i' works similar for old-style and modern function headers.
* Additional C99/C++ keywords -- from 'alignas' to 'thread_local' -- are
supported internally.
* '@i'nclude file 'iso_types.w' for numeric types (in addition to
'c++lib.w').
* Countless code modifications, including some corrections amd
improvements.
Thanks and cudos to Github user "@texdraft" for numerous contributions
to this feature release!

In the course of the "2021 TeX tuneup", Don Knuth kindly transferred
the responsibility for CWEB to me; see the original CWEB home page
(https://www-cs-faculty.stanford.edu/~knuth/cweb.html), section
"CWEB 4.0" and the updated CWEB development project
(https://github.com/ascherer/cweb).
This first new release draws heavily on the multi-decade work collected
in my "CWEBbin" project (https://github.com/ascherer/cwebbin). I moved
(almost) all stuff from the "*-patch.*" changefiles into the new CWEB
sources and applied all of the "*-ansi.*" changes as well.
Moreover, I made "common.h" the full interface of "common.w" in order to
avoid code redundancy. And I tried to fix as many of the bugs reported
by email to DEK and/or tex-k@tug.org.
In total, "make; make cautiously; make fullmanual" runs flawlessly with
GCC on Linux and with LLVM on MacOS.
After the release of "CWEB 4.0", also "CWEBbin 2021" has also been fully
revised. Thousands of lines of changefiles could be purged. What's
left are the clearcut extensions for CWEB and the additional stuff for
integration in "TeX Live 2021".

It's a long and winded road to run CTWILL on its own source code in
order to produce a nice and user-friendly rendering in PDF. :o)
