calc v2.14.3.5 release

The following are the changes in this release:

Under macOS, to reduce dependency chains, we remove functions
and data that are unreachable by the entry point or exported
symbols.  In particular, the macOS linker is used with both
"-dead_strip" and "-dead_strip_dylibs".

The libcalc shared library is now linked with libcustcalc.

calc 2.14.3.4 release

The following are the changes in this release:

Fix typo in the `make debug` Makefile rule.

Improved .gitignore to ignore .static, calc-static,
sample_many-static and sample_rand-static.

Improved error messages when trying to compile with
with one calc type (when BLD_TYPE=calc-dynamic-only or
BLD_TYPE=calc-static-only) and install with the other.

When installing with BLD_TYPE=calc-static-only, the
installed calc and calc-static are links to each other.
Thanks to GitHub user @TurtleWilly for this suggestion.

The dynamic shared libraries are not installed if they are not
built.  So when installing with BLD_TYPE=calc-static-only, the
install rule will not attempt to install dynamic shared libraries.
Thanks to GitHub user @TurtleWilly for bringing to our attention,
problems related to building a statically linked calc under macOS.

Updated comments in Makefile.local for how to Diagnosing memory,
thread, and crash issues under RHEL and macOS.

We no longer support the Makefile variable ${ALLOW_CUSTOM} to be empty.
Normally ${ALLOW_CUSTOM} is:

ALLOW_CUSTOM= -DCUSTOM

Now, to disable custom disable custom even if -C is given, use:

ALLOW_CUSTOM="-UCUSTOM"

Dropped support of Makefile.simple and custom/Makefile.simple.
The calc version 2.14.3.0 is the last release that supported
the Makefile.simple and custom/Makefile.simple files.
Now, a make that supports makefile conditional syntax is required.
The simple target, a target that only was used for Makefile.simple
was removed.

Moved makefile variables that configure calc and configure how to
compile calc from Makefile into a new Makefile.config file.

The Makeifle includes the Makefile.config file.
The cal/Makeifle includes the Makefile.config file.
The cscript/Makeifle includes the Makefile.config file.
The custom/Makeifle includes the Makefile.config file.
The help/Makeifle includes the Makefile.config file.

Now, the Makefile.config file will consistently configure
calc and how calc is compiled and built by all calc Makefiles.
The custom/Makefile no longer includes Makefile.

The platform target section from the old Makefile has been moved
to a new file, Makefile.target.  Improved the format and comments
in target information.

The Makeifle includes the Makefile.target file.
The cal/Makeifle includes the Makefile.target file.
The cscript/Makeifle includes the Makefile.target file.
The custom/Makeifle includes the Makefile.target file.
The help/Makeifle includes the Makefile.target file.

Now, the Makefile.target file will consistently set
target information for all calc Makefiles.

The cal/Makeifle includes the Makefile.local file.
The cscript/Makeifle includes the Makefile.local file.
The custom/Makeifle includes the Makefile.local file.
The help/Makeifle includes the Makefile.local file.

Thus, one may modify or append many Makefile variables
in all calc Makefiles.

Removed the ${CAL_PASSDOWN}, ${HELP_PASSDOWN}, ${HELP_PASSDOWN},
${CSCRIPT_PASSDOWN} Makefile variables as the new Makefile
include files keep Makefile variables in sync.

Fixed the ability of calc to compile when CUSTOM is undefined
(i.e., -UCUSTOM).  The libcustcalc is always built, regardless
of the $(ALLOW_CUSTOM} Makefile variable.  However when CUSTOM
is undefined, the bulk of custom functions are not defined.

Dropped the use of Makefile variable ${SET_INSTALL_NAME}.
Under macOS it was always needed, elsewhere it was not.

Added Makefile variable ${VER} to hold the calc major release version.
The calc major release version is a 3 level version (x.y.z).

Under macOS, the current version of both libcalc and libcustcalc
shared libraries are set to the current calc major release version.

Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the macOS linker is used with "-dead_strip" by default.

While calc on macOS will execute if linker used with "-dead_strip_dylibs"
and CUSTOM is defined, other applications that use libcalc but not
libcustcalc (such as sample_many and sample_rand) will fail to execute
due to missile symbols.  Therefore "-dead_strip_dylibs" is not used
by default when ALLOW_CUSTOM is "-DCUSTOM" under macOS.
Thanks to GitHub user @TurtleWilly for bringing to our attention,
problems related to use of  "-dead_strip_dylibs".

When installing shared libraries, libcalc.x.y.z will be a link
to the libcalc shared library and libcustcalc.x.y.z will be a link
to the libcustcal shared library.

calc 2.14.3.1 release

The following are the changes in this release:

IMPORTANT: This is just a test release. Please do not use.

calc 2.14.3.0 release

The following are the changes in this release:

Updated COPYING to include the actual text of "The Unlicense".
Made minor formatting changes to the file.

The Darwin specific ${DARWIN_ARCH}, thay by default was unset,
is now the ${ARCH_CFLAGS} Makefile variable.  Comments about
various "-arch name" have been moved to the ${ARCH_CFLAGS} area.

For old Apple Power PC systems, the following is added:

COMMON_CFLAGS+= -std=gnu99
COMMON_LDFLAGS+= -std=gnu99
ARCH_CFLAGS+= -arch ppc

Old Apple Power PC systems should be detected by the
"uname -p" command returning "powerpc".  One may force the
Power PC mode by adding to the end of any make command:

make ...make_args... target=Darwin arch=powerpc

or by adding the following in the Makefile.local file:

target= Darwin
arch= powerpc

Improved the output of the calcinfo rule by adding echos
of various uname values as well as some top Makefile variables.

Fixed the BUGS file with respect to using `make debug`.

Added a final ls of `debug.out` for `make debug`.

calc 2.14.2.2 release

The following are the changes in this release:

Removed references to obsolete Email addresses.

macOS Darwin defaults LCC to "cc".

calc 2.14.2.1 release

The following are the changes in this release:

Added cal/fnv_tool.cal, a calc resource file defining:

find_fnv_prime(bits)
deprecated_fnv0(bits,fnv_prime,string)
fnv_offset_basis(bits,fnv_prime)
fnv1a_style_hash(bits,fnv_prime,prev_hash,string)

Fixed sorted order of cal/README.

calc 2.14.2.0 release

The following are the changes in this release:

Ported calc to the s390x IBM Mainframe running RHEL9.1.

Added cal/splitbits.cal:

splitbits(x, b)

Given an integer x, split the value into a list of integers,
each of which is at most b bits long.

The value b must be an integer > 0.

The number of elements in the returned list is:

    ceil((highbit(x) + 1) / b)

If x == 0, then a list of 1 element containing 0 is returned.

If x < 0, then the two's compliment of abs(x) is returned.
Even though calc represents negative integers as positive values
with sign bit, the bits returned by this function are as if
the integer converted as if the integer was a two's compliment value.

See also the help command:

    ; help resource

calc 2.14.1.6 release

The following are the changes in this release:

Fixed version numbers in two cases in CHANGES that referred
to the 2.14.2.x instead of 2.14.1.x.

Rename MINGW Makefile variable (a holdover from MINGW32_NT-5.0)
to OSNAME.

Fixed FUNCPTR typedef in hist.c to fix deprecated compiler warnings.

Fixed when USE_READLINE, READLINE_LIB, READLINE_EXTRAS, and
READLINE_INCLUDE are set to empty (disable use of the GNU-readline
facility).

Fix cases of spaces before tabs in Makefile and Makefile.simple.

Fixed obsolete references to the atoz() in LIBRARY to use the
correct internal function name of str2z().

Fixed obsolete references to the atoq() in LIBRARY to use the
correct internal function name of str2q().

Document in help/unexpected that * operator has has a higher
precedence than << in calc, which differs from C.  Thanks
goes to GitHub user @inguin for pointing put this difference.

calc 2.14.1.5 release

The following are the changes in this release:

Fixed version numbers in two cases in CHANGES that referred
to the 2.14.2.x instead of 2.14.1.x.

Rename MINGW Makefile variable (a holdover from MINGW32_NT-5.0)
to OSNAME.

Fixed FUNCPTR typedef in hist.c to fix deprecated compiler warnings.

Fixed when USE_READLINE, READLINE_LIB, READLINE_EXTRAS, and
READLINE_INCLUDE are set to empty (disable use of the GNU-readline
facility).

Fix cases of spaces before tabs in Makefile and Makefile.simple.

calc 2.14.1.4 release

The following are the changes in this release:

Updated COPYING file to indicate that these files are now
covered under "The Unlicense" (see https://unlicense.org):

    sha1.c
    sha1.h
    cal/dotest.cal
    cal/screen.cal

Updated help/credit to match the above changes to COPYING.

Updated CONTRIB-CODE and calc.man to refer to using GitHub pull requests
for contributing to calc (instead of using Email).

Updated BUGS and calc.man to refer to using GitHub issues
for reporting calc bugs (instead of using Email).

Updated QUESTIONS and calc.man to refer to using GitHub issues
for asking calc questions (instead of using Email).

Fixed Makefile.local command example to refer to overriding the
Makefile variable DEBUG (instead of CDEBUG).

Fixed all make chk ASAN warnings under macOS 13.2.1 when calc is compiled
with the following uncommented lines in Makefile.local:

DEBUG:= -O0 -g
CFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
LDFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
CALC_ENV+= ASAN_OPTIONS=detect_stack_use_after_return=1

Improved how pointers to functions are declared for the builtins
array in func.c to avoid function declarations without a prototype
that is now deprecated in C.

Improved how pointers to functions are declared for the opcodes
array in opcodes.c to avoid function declarations without a prototype

Replaced use of egrep with grep -E in Makefiles.

Fixed cases where variables were set but not used in symbol.c, calc.c,
and the main function in func.c as used by funclist.c.

Added rule name to "DO NOT EDIT -- generated by the Makefile" lines
in constructed files.

Test if <sys/vfs.h> exists and set HAVE_SYS_VFS_H accordingly
in have_sys_vfs.h.  Added HAVE_SYS_VFS_H to allow one to force
this value.

Test if <sys/param.h> exists and set HAVE_SYS_PARAM_H accordingly
in have_sys_param.h.  Added HAVE_SYS_PARAM_H to allow one to force
this value.

Test if <sys/mount.h> exists and set HAVE_SYS_MOUNT_H accordingly
in have_sys_mount.h.  Added HAVE_SYS_MOUNT_H to allow one to force
this value.

Test if the system as the statfs() system call and set HAVE_STATFS
accordingly in have_statfs.h.  Added HAVE_STATFS to allow one
to force this value.

The pseudo_seed() function will also try to call statfs() if
possible and permitted by the HAVE_STATFS value.

Test if makedepend command is available before trying to build
the Makefile dependency list via "make depend".
