Added charbit.h to define CALC_CHARBIT which is either CHAR_BIT
from <limits.h> or 8 or a value set by the Makefile variable
CALC_CHARBIT. Added have_limits.h to determine if <limits.h>
is a system include file.
Drop support for CLOCK_SGI_CYCLE.
Improved seed() generation. Improved some comments in seed.c.
Added have_environ.c to build have_environ.h in order to
determine if:
extern char **environ; /* user environment */
is an valid external symbol.
Added notes to help/unexpected about:
display() will limit the number of digits printed after decimal point
%d will format after the decimal point for non-integer numeric values
%x will format as fractions for non-integer numeric values
fprintf(fd, "%d\n", huge_value) may need fflush(fd) to finish
Fixed Makefile dependencies for the args.h rule.
Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
Sort lists of standard tool Makefile variables and remove duplicates.
Declare the SHELL at the top of Makefiles.
Fixed the depend rule in the custom Makefile.
Improved the messages produced by the depend in the Makefiles.
Changed the UNUSED define in have_unused.h to be a macro with
a parameter. Changed all use of UNUSED in *.c to be UNUSED(x).
Removed need for HAVE_UNUSED in building the have_unused.h file.
CCBAN is given to ${CC} in order to control if banned.h is in effect.
The banned.h attempts to ban the use of certain dangerous functions
that, if improperly used, could compromise the computational integrity
if calculations.
In the case of calc, we are motivated in part by the desire for calc
to correctly calculate: even during extremely long calculations.
If UNBAN is NOT defined, then calling certain functions
will result in a call to a non-existent function (link error).
While we do NOT encourage defining UNBAN, there may be
a system / compiler environment where re-defining a
function may lead to a fatal compiler complication.
If that happens, consider compiling as:
make clobber all chk CCBAN=-DUNBAN
as see if this is a work-a-round.
If YOU discover a need for the -DUNBAN work-a-round, PLEASE tell us!
Please send us a bug report. See the file:

for how to send us such a bug report.
Added the building of have_ban_pragma.h, which will determine
if "#pragma GCC poison func_name" is supported. If it is not,
or of HAVE_PRAGMA_GCC_POSION=-DHAVE_NO_PRAGMA_GCC_POSION, then
banned.h will have no effect.
Fixed building of the have_getpgid.h file.
Fixed building of the have_getprid.h file.
Fixed building of the have_getsid.h file.
Fixed building of the have_gettime.h file.
Fixed building of the have_strdup.h file.
Fixed building of the have_ustat.h file.
Fixed building of the have_rusage.h file.
Added HAVE_NO_STRLCPY to control if we want to test if
the system has a strlcpy() function. This in turn produces
the have_strlcpy.h file wherein the symbol HAVE_STRLCPY will
be defined, or not depending if the system comes with a
strlcpy() function.
If the system does not have a strlcpy() function, we
compile our own strlcpy() function. See strl.c for details.
Added HAVE_NO_STRLCAT to control if we want to test if
the system has a strlcat() function. This in turn produces
the have_strlcat.h file wherein the symbol HAVE_STRLCAT will
be defined, or not depending if the system comes with a
strlcat() function.
If the system does not have a strlcat() function, we
compile our own strlcat() function. See strl.c for details.
Fixed places were <string.h>, using #ifdef HAVE_STRING_H
for legacy systems that do not have that include file.
Added ${H} Makefile symbol to control the announcement
of forming and having formed hsrc related files. By default
H=@ (announce hsrc file formation) vs. H=@: to silence hsrc
related file formation.
Explicitly turn off quiet mode (set Makefile variable ${Q} to
be empty) when building rpms.
Improved and fixed the hsrc build process.
Forming rpms is performed in verbose mode to assist debugging
to the rpm build process.
Compile custom code, if needed, after main code is compiled.
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.

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!
