The following are the changes in this release:
Fixed missing <string.h include in have_fpos_pos.c.
Change calc version from 2.14.1.2 to 2.14.2.3 as part of a test to
build calc RPMs on a reference RHEL8.7 platform (formerly a RHEL7.9
platform).
Otherwise, the probe result changes with compilers which do not
support implicit function declarations, a language feature that
was removed from C in 1999.
The following are the changes in this release:
Restored use of the #define FPOS_POS_LEN symbol. This refers to
the length of the __pos element (if the __pos element exists),
the fpos_t type (if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little
Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR
is defined).
Changed #define HAVE_FPOS to HAVE_FGETSETPOS.
Corrected comment in have_fpos_pos.h. The HAVE_FPOS_POS symbol was
NOT related to fgetpos & fsetpos but rather if we we have an __pos
element in FILEPOS.
Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS.
Improved comments in have_fpos_pos.h to show why and how
HAVE_FPOS_POS, FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed.
Changed showfiles builtin to print sizes cast to (long int) with
the "%ld" printf format to avoid implementations that do not support
the "%lld" printf format specifier.
Renamed have_fpos.h to have_fgetsetpos.h. Renamed CALC_HAVE_FPOS_H
to CALC_HAVE_FGETSETPOS_H. The make install and the olduninstall
rules remove the any old have_fpos.h that was previously installed.
Added swap_HALFs(dest, src, len) function to byteswap.c.
Calc can now handle Big Engian file position sizes that are a
multiple of BASEB bits in length. Before handle Big Engian file
positions could only be 32 and 64 bits in length. This will allow,
for example, a Big Engian file position size of 128 (assuming that
128/BASEB is is an integer).
Temporary workaround for musl libc systems such as gentoo Linux that
allows them to compile calc and successfully run the regression test.
Restored use of the #define FPOS_POS_LEN symbol. This refers to the
length of the __pos element (if the __pos element exists), the fpos_t type
(if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little
Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR
is defined).
Changed #define HAVE_FPOS to HAVE_FGETSETPOS.
Corrected comment in have_fpos_pos.h. The HAVE_FPOS_POS symbol was NOT
related to fgetpos & fsetpos but rather if we we have an __pos element
in FILEPOS.
Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS.
Improved comments in have_fpos_pos.h to show why and how HAVE_FPOS_POS,
FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed.
Changed showfiles builtin to print sizes cast to (long int) with the
"%ld" printf format to avoid implementations that do not support the
"%lld" printf format specifier.
Added full_debug rule to Makefile. This does the work of the
old debug rule in a more verbose mode by using Q= H=@ S= E= V=@.
The debug rule in the Makefile now pre-removes debug.out and then
runs make full_debug sending stdout and stderr to debug.out. It then
prints a few instructions about filing a GitHub issue bug report.
The following are the changes in this release:
Added a few remarks on calc version numbers to version.c.
Fixed how fposval.h is built. On a number of systems, the fposval.c
file failed to compile incorrectly. This caused problems for systems in
which fposval.h.def was not correct.
Fixed how have_memmv.h is built. On a number of systems, the have_memmv.c
file failed to compile incorrectly, producing a potentially incorrect
have_memmv.h file for such systems.
Fixed how align32.h is built. On a number of systems, the align32.c
file failed to compile incorrectly, producing a potentially incorrect
align32.h file for such systems.
Fixed how have_newstr.h is built. On a number of systems, the have_newstr.c
failed to compile incorrectly, producing a potentially incorrect
have_newstr.h file for such systems.
Fixed how have_strdup.h is built. On a number of systems, the have_strdup.c
file failed to compile incorrectly, producing a potentially incorrect
have_strdup.h file for such systems.
Fixed how have_strlcat.h is built. On a number of systems, the have_strlcat.c
file failed to compile incorrectly, producing a potentially incorrect
have_strlcat.h file for such systems.
Fixed how have_strlcpy.h is built. On a number of systems, the have_strlcpy.c
file failed to compile incorrectly, producing a potentially incorrect
have_strlcpy.h file for such systems.
Fixed how have_uid_t.h is built. On a number of systems, the have_uid_t.c
file failed to compile incorrectly, producing a potentially incorrect
have_uid_t.h file for such systems.
Fixed how have_uid_t.h is built. On a number of systems, the have_uid_t.c
file failed to compile incorrectly, producing a potentially incorrect
have_uid_t.h file for such systems.

The following are the changes from calc version 2.14.1.0 to date:
Fixed alignment of show item section of help command.
Bug fix: While 0^0 == 1, now for y > 0, 0^y == 0.
Adjusted cal/test8900.cal to reflect this bug fix.
Added tests to cal/regress.cal to help verify bug fix is fixed.
Changed /*NOTREACHED*/ to not_reached(); and use "attribute.h".
Added .PHONY rule, just after all rule, to Makefiles.
Fixed an improper indentation issue.
Changed Makefile to set shell before setting the SHELL Makefile
variable.
Added text to HOWTO.INSTALL to help people with systems that
lack the readline package.
Trimmed long line in the CONTRIBUTING.md file.
The following are the changes in this release:
Fixed typo in Makefile.local comment.
Established a tagging procedure for a production release.
Production git tags will be of the form:
prod-2.x.y.z
We apologize for the calc v2.14.0.12 source tarball that was missing
critical files. While the executable was well tested, our release
process was deficient.
We are improved our release process and added tests during the release
procedure to help verify that we are not regressing in to the "v2.14.0.12
source tarball" issue, among other things.
Depending on how things do, you might is several releases come out over
a short period of time. The core of calc isn't changing, so the calc
executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.
=-=
The following are the changes in this release:
Minor tweak to seed() builtin. Updated help/srand and help/srandom.
Moved Makefile.ship into Makefile.
Removed custom/Makefile.head and custom/Makefile.tail.
The custom/Makefile is now part of source and includes Makefile.
In particular, custom/Makefile makes use of the 'middle' of
the new top level Makefile where calc's top level Makefile
variables are defined.
Makefile.simple and custom/Makefile.simple are now part of the source
and are constructed from Makefile and custom/Makefile respectively.
The Makefile.simple and custom/Makefile.simple avoid using GNU
conditionals. They may be used with older/classic make commands.
Makefile.local will include comments about how to better use
it. Between releases, Makefile.local at the top of the master branch
will contain how we typically build calc and test calc (FYI: we
normally enable things such as -Werror -Wextra -pedantic). When we
push out a release, Makefile.local will be stripped of non-comment
lines. Thus, releases of calc, and, released "calc*.src.rpm"
files and the source tarballs, will have a Makefile.local with
only comments.
The "README.*" files and "HOWTO.INSTALL" file have been updated.
By default, compiler warnings have been turned up. The Makefile
variable ${CCWARN} now defaults to:
CCWARN= -Wall -Wextra -pedantic
The previous level of compiler warnings can be easily restored by
adding to Makefile.local:
CCWARN:= -Wall
The readline, history and ncurses libraries are now default.
The Makefile variables ${USE_READLINE}, ${READLINE_LIB}, and
${READLINE_EXTRAS} now default to:
USE_READLINE= -DUSE_READLINE
READLINE_LIB= -lreadline
READLINE_EXTRAS= -lhistory -lncurses
The previous mode where readline, history and ncurses libraries
were not compiled in by default can be easily restored by
adding to Makefile.local:
USE_READLINE:=
READLINE_LIB:=
READLINE_EXTRAS:=
We have renamed "stable" as "production".
We have renamed "unstable" as "tested".
On the web site:
http://www.isthe.com/chongo/src/calc/
these files has been renamed:
2.x.y.z_IS_LATEST_STABLE ==> 2.x.y.z_IS_LATEST_PRODUCTION
2.x.y.z_IS_LATEST_UNSTABLE ==> 2.x.y.z_IS_LATEST_TESTED
The terms 'stable' and 'unstable' were both misleading and
inaccurate. For details see the new documention file:
README.RELEASE
See also the help command:
; help release
Fixed bug impacting how have_ustat.h was formed.
Updated help/archive to reflect GitHub use.

critical files. While the executable was well tested, our release
process was deficient.

executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.
We made several changes to the Makefiles. We also added a new
README.RELEASE document (see "help release") that is a work in
progress. Along the way we discovered a few things that needed to be
updated in documentation.
See the CHANGES file for details.
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.
Unfortunately due to the complex dependency issues between
Makefile, Makefile.ship and custom/Makefile, parallel GNU make
is NOT recommended. Sorry (tm Canada) :)
Replaced /usr/local with the use of ${PREFIX} in calc Makefiles.
The ${PREFIX} is not the same as ${T}. The ${T} specifies
a top level directory under which calc installs things.
While usally ${T} is empty, it can be specific path
as if calc where "chrooted" during an install.
The ${PREFIX} value, during install, is a path between
the top level ${T} install directory and the object
such as an include file.
Corrected a few more typos in Makefile comments.
Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles. This information discusses the various
Makefiles found in the calc source.
Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.
For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:
# SRC: ... some message about the origin ...
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:
BUGS
or the URL:
http://www.isthe.com/chongo/tech/comp/calc/calc-bugrept.html
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 Makefile dependenies 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.
