Fixed a mistake in "help intro" where some inserted text
changed the value of "." and thus made the next result
incorrect.
Clarified in "help factor" that 1 is returned if no
factor below the limit was found.
Removed Makefile variable ${MAKEFILE_REV}.
The missing cscript/square.calc file has been restored.
Fixed compiler errors and warnings related to GCC.
In particular, gcc/9.3.1 and gcc/10.2.1 now compile
calc without any compiler errors or warnings,
even with -Werror -Wextra -pedantic.
To print out information about the calc compliation
environment, we added the following make rule:
make calcinfo
Improved how 'make debug' operates.
Moved help/contrib to CONTRIB-CODE. The help/contrib file
is now build from a copy of CONTRIB-CODE.
Created a new calc bug report Email address. Created a new calc
question Email address. Created a new calc contribution Email
address. See the BUGS file for details.
Added "help questions" to print the QUESIONS help file.
If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the direcgory by the $CALCHISTFILE
environment variable.
If the environment variable $CALCCUSTOMHELP is defined and is
non-empty, then custom calc help files will be in the direcgory
by the $CALCCUSTOMHELP environment variable.
The calc-tester mailing list has been retired. See:

GCC 7 Added a warning for implicit fallthroughs in switch cases.
It's enabled by -Wextra, and treated as an error due to -Werror so
compilation fails on GCC 7 and higher.
See -Wimplicit-fallthrough in the GCC manual.
The following are the changes in this release:
For historical purposes, in lucas.cal, gen_v1(1, n) always returns 4.
Fixed some compiler warnings, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Added work around for a gcc warning bug, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Fixed errors in various help files such as:
mat randbit seed srandom types
Removed the MAXSTRING symbol because it was no longer used by calc.
Increased HIST_SIZE (depth of the history stack) from 10k to 32k.
Increased TTYSIZE (reallocation size for terminal buffers) from 100 to 8191.
Increased MAXDEPTH (maximum depth of input stack) from 10 to 255.
Increased interactive input buffer size from 1024 to 256k. This has the
effect of increasing the maximum length of an input line from a tty.
This helps with an interactive bug that was reported by Ruslan Kabatsayev
(b7 dot 10110111 at gmail dot com).
The calc man page indicates that -d also disables the printing of the
leading tilde.
Added information to "help command" about how to silence messages
while reading calc resource files.
Fixed an error message buffer overflow thanks to a report by
Frank Peters <nlp at northernlightsphoto dot biz>.
Replaced all use of the C funcion sprintf() with snprintf().
Replaced all use of the C funcion vsprintf() with vsnprintf().
Replaced all DONT_HAVE_VSPRINTF with DONT_HAVE_VSNPRINTF.
Replaced all Makefile var ${HAVE_VSPRINTF} with ${HAVE_VSNPRINTF}.
Some folks might think: “you still use RCS”?!? And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)
Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.
RCS served us well. But now it is time to move on. And so we are
switching to git.
Calc releases produce a lot of file changes. In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
