4d32b138ed change libcalc dynamic library to link with libcustcalc
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.

b0f19c1011 Release v2.14.3.4
Fixed rpm spec file.

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.

1e2d02e449 changed macOS to not use "-dead_strip_dylibs"
The macOS ld documentation states that option should not be used
when linking against a dylib which is required at runtime for some
indirect reason such as the dylib has an important initializer.
The libcustcalc appears to have such an initializer.

d89ea78104 prep for calc version 2.14.1.4
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.

f4f19f21dc Add config("complex_space") to control spaces around + or - in complex values
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements.  Updated cal/regress to test
config("tilde_space").

Added config("complex_space", boolean).  The "complex_space" controls
whether or not a space (' ') is printed before and after the + or -
in complex values.

By default, config("complex_space") is false.

For example, with the default, config("complex_space", 0):

    ; asin(2)
	    1.57079632679489661923-1.31695789692481670863i

With config("complex_space", 1):

    ; asin(2)
	    1.57079632679489661923 - 1.31695789692481670863i

NOTE: Use of config("complex_space", 1) can break printing and scanning
      of fractional values via "%r".

NOTE: Use of config("complex_space", 1) can break printing and scanning
      of complex values via "%c".

Added config("complex_space", boolean) to help/config, along with

Added config("fraction_space", boolean).  The "fraction_space" controls
whether or not a space (' ') is printed before and after fractions.

For example, with the default, config("fraction_space", 0):

    ; base(1/3),
    ; 1/7
            1/7

With config("fraction_space", 1):

    ; base(1/3),
    ; 1/7
            1 / 7

NOTE: Use of config("fraction_space", 1) can break printing and scanning
      of fractional values via "%r".

NOTE: Use of config("fraction_space", 1) can break printing and scanning

0d99ba54d8 Change default to print space after the approximation tilde
Added config("tilde_space", boolean).  The "tilde_space" controls

By default, config("tilde_space") is true, which is a change
from past behavior.  For example, now:

    ; 1/3
	    ~ 0.33333333333333333333

With config("tilde_space", 0):

    ; 1/3
	    ~0.33333333333333333333

To disable "tilde_space", use config("tilde_space", 0) on the
command line and/or use config("tilde_space", 0),; in your ~/.calcrc.
Thanks goes to <GitHub use ljramalho> for this suggestion.

Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements.  Updated cal/regress to test
config("tilde_space") and to account for the new default.

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.

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.

340c1990ce Checkpoint on fixing compiling with musl gentoo
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).
