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".

calc 2.14.1.3 release

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).

calc 2.14.1.2 release

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.

calc 2.14.1.1 release

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.
