calc 2.14.1.0 release

The following are the changes in this release:

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.

Release v2.14.0.14

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

calc 2.14.0.13 release

Release v2.14.0.13

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.

Removed constructed help file that incorrectly added as a src file.

The following are the changes in this release:

Made major changes to our release process in order to avoid
missing critical files that happened in calc v2.4.0.12.

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, BUGS, HOWTO.INSTALL to reflect GitHub use.

calc 2.14.0.12 release

The following are the changes in this release:

Fixed a number of typos.

Drop support for SunOS, IRIX and MINGW32_NT-5.0 targets.
Drop support for CLOCK_SGI_CYCLE.  Drop testing for __MSDOS__.

Minor improvement of various help files.  Made format of help
files more consistent.

Corrected a few comments in zrandom.c, including a case where
the comment referred to 1007 when it should have used 2^32.

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.

Fixed documentation that referred to the old additive 55
generator.  We have been using the subtractive 100 in place
of the additive 55 generator for a while now.

Fixed depend rule for custom/Makefile.

Fixed how Makefile variable SHELL is set on macOS vs. Linux.
Using /bin/sh on macOS due to how zsh treats globs by default.

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.

Compiling now tests for _WIN64 as well when testing for _WIN32.

Now assuming that <stdio.h> is available under _WIN32 and _WIN64.

Added some preliminary notes about attempts to compile calc
under Windows 11.

BTW: While we are unable to use Windows 11, we welcome
     Windows 11 developers to try compiling calc natively
     (instead of via a Linux virtual machine).  If you are
     able to compile Windows 11 natively, we would welcome
     GitHub pull requests showing any needed modifications:

	https://github.com/lcn2/calc/pulls

     Please also add notes to the 'Compiling calc under Windows 11'
     section in README.WINDOWS file.

We added Makefile.simple as part of the master branch source
to help those who may be using a make tool that does not support
GNU Make-like features such as "ifeq" and ":=".

Fixed incorrect ustat_dev member ref in seed() builtin that
was part of the unreleased calc v2.12.0.11.

calc 2.14.0.10 release

The following are the changes in this release:

Due to issues with clang and Apple Silicon, ARCH_CFLAGS is now,
by default, empty:

ARCH_CFLAGS=

If you want to use, say, -march=native, then either change
the Makefile or make with:

make all ARCH_CFLAGS='-march=native'

Added arch and hardware as GNU Makefile computed values.
As with ${target}, ${arch} and ${hardware} is computed by uname:

target: uname -a
arch: uname -p
hardware: uname -m

Fixed compiling calc on Apple Silicon with homebrew.  On Apple
Silicon, HomeBrew installs on into a different location.  The
Makefile checks if ${hardware} is arm64 and adjusts the location
of libraries such as readline and history accordingly.

Pluged a number of memory leaks.

Fixed a few cases where v_subtype was not properly initialuzed.

Improved the way that internal pre-defined constants are managed.
Removed unused internal pre-defined constants.  Added code to
prevent an internal pre-defined constant (that was never allocated)
from being freed.

Remove unnecessary spaces inbetween or next to tabs.

Update copright dates to account for 2021 modifications.

calc 2.14.0.9 release

The following are the changes in this release:

Due to issues with clang and Apple Silicon, ARCH_CFLAGS is now,
by default, empty:

ARCH_CFLAGS=

If you want to use, say, -march=native, then either change
the Makefile or make with:

make all ARCH_CFLAGS='-march=native'

Added arch and hardware as GNU Makefile computed values.
As with ${target}, ${arch} and ${hardware} is computed by uname:

target: uname -a
arch: uname -p
hardware: uname -m

Fixed compiling calc on Apple Silicon with homebrew.  On Apple
Silicon, HomeBrew installs on into a different location.  The
Makefile checks if ${hardware} is arm64 and adjusts the location
of libraries such as readline and history accordingly.

calc 2.14.0.8 release

The following are the changes in this release:

Identical to v2.14.0.7: now declared a stable release.

calc 2.14.0.7 release

The following are the changes in this release:

Fizzbin is a better word. :-)

The help and man builtin commands now return an error when a
help file cannot be opened, such as when there is no help file.

Added palindrome.cal resource file.  For example, to find the
largest (highly probable) prime palindrome under 280 decimal
digits (text tweet limit):

prevprimepal(1e280)

calc 2.14.0.6 release

The following are the changes in this release:

Fixed typo in cal/statistics.cal thanks to a report by <GitHub user
dennisaldea>.

Fixed an old Windoz pun in README.WINDOWS as requested by <GitHub
user marcodegio>.

Fixed a really obscure bug in the internal initconstants()
function of const.c that has been sitting for over 31 years!

We are amazed that nobody has encountered this bug before
now.  Nevertheless, our very extensive regression and
multi-architecture testing found the bug.  Now, after all
those years, it is fixed.

Fixed issues identied by the default CodeUL GitHub security code scan:

Wrong type of arguments to printf in have_fpos_pos.c
Multiplication result converted to larger type in zfunc.c

calc 2.14.0.3 release
