83adfaa720 Removed compiler confusing setjmp() call
In pseudo_seed(), we removed a call to setjmp() that was only
there to add more information to mix into the seed.  For compilers
such as gcc that used -Wclobbered, the call to setjmp() gave the
impression that the hash_val might be clobbered by a longjmp().
Where there is no longjmp() that would use the previous setjmp(),
the gcc compiler has nil ways to notice that. So to avoid confusion
we removed the setjmp() call.  Thanks to <GitHub user mattdm> for
raising this potential concern.

ef6a30c9c9 Fixed how the original TTY state is preserved
In find_tty_state(), we changed how we expand fd_orig as an original
pre-modified copy of fd_setup.  We realloc the fd_orig array and copy
the fd_setup into it first, before touching the fd_setup array.

3aaad95443 Fixed a use after free bug
Fixed a -Wuse-after-free warning that identified a call to realloc() in
find_tty_state() could move the fd_setup array.  Thanks goes to <GitHub
user mattdm> for reporting this bug!

49c6a8218c Release calc v2.14.1.2
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.

dce2c6f0ee Improve the make debug rule
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.

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.

b97093e58c Fix calc man page \-escape, add cal/comma.cal
Fixed a \-escape bug in calc(1) man page.

Added cal/comma.cal:

    Convert numbers into strings with 3-digit group and integer-fraction
    separators.

    If the value is an integer, the integer-fraction separator is not used.

    str_comma(x, [group, [decimal]])

	Convert x into a string.

	If group is given and is a string, group will be used as
	the 3-digit group separator, otherwise the default 3-digit
	group separator will be used.

	If decimal is given and is a string, group will be used as
	the integer-fraction separator, otherwise the default
	integer-fraction separator will be used.

	The decimal and group arguments are optional.

    set_default_group_separator(group)

	Change the default 3-digit group separator if group is a string,
	otherwise the default 3-digit group separator will not be
	changed.  Return the old 3-digit group separator.

    set_default_decimal_separator(decimal)

	Change the default 3-digit group separator if decimal is a
	string, otherwise the default integer-fraction separator
	will not be changed.  Return the old integer-fraction separator.

    print_comma(x, [group, [decimal]])

	Print the value produced by str_comma(x, [group, [decimal]])
	followed by a newline.

	If the str_comma() does not return a string, nothing is printed.

	The decimal and group arguments are optional.

	The value produced by str_comma() is returned.

    fprint_comma(fd, x, [group, [decimal]])

	Print the value produced by str_comma(x, [group, [decimal]]),
	without a trailing newline, on file fd.

	If the str_comma() does not return a string, nothing is printed.

	If fd is not an open file, nothing is printed.

	The decimal and group arguments are optional.

	The value produced by str_comma() is returned.

ffd4422870 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.

progress. Along the way we discovered a few things that needed to be
updated in documentation.

0f6efb29bb Release v2.14.0.12
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.
