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

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.
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.
Drop support for CLOCK_SGI_CYCLE.
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.
The :-separated default CALCRC value has been reversed.
The default CALCRC was:
${CALC_SHAREDIR}/startup:~/.calcrc:./.calcinit
The default CALCRC is now:
./.calcinit:~/.calcrc:${CALC_SHAREDIR}/startup
See "help environment" for details.
The following are the changes in this release:
Fixed typo (missing quotes) in the env rule.
Fixed intendation problem in CHANGES.
Combined 2.12.9.1 changes into the 2.12.8.2 to 2.12.9.0
range, and thus renamed the range to 2.12.8.2 to 2.12.9.1.
Fixed issues related to building Makefile.simple.
Fixed how the Makefile variable MANPATH is set for macOS.
Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles. This information discusses the various
Makefiles found in the calc source.
Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.
For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:
# SRC: ... some message about the origin ...
Fixed how the calc(1) man page is installed under macOS.
Fixed how calc man page in ${CATDIR} is formed.
Fixed how Makefile.simple is formed.
Fixed the #! calc script argument processing. The initial #!
line must end in a -f. For example, if calc is in /usr/local/bin/calc,
then the following would be the first line of a calc script:
#!/usr/local/bin/calc -f
...
It is common that -q be usde with a calc script, so assuming the
same /usr/local/bin/calc path:
#!/usr/local/bin/calc -q -f
...
Use of -s in the #! first line of a calc script is not needed
since -f implies -f.
The argv() will now return values more typical of C's main().
Before it returned one less than the number of arguments. Now,
for example, when calc is given 2 args, argv() will return 3.
The value of argv(0) will be the path to calc, or in the
case of a #! calc cscript, it will return the name of the script.
Updated the calc man page and help/argv to reflect the
above changes.
Improved the formatting of the calc man page.
Fixed the formation of the win32 sub-directory via the win32_hsrc
Makefile rule.
Due to incompatible changes to the argv() function, and #! calc
scripts, we are setting the version to the next minor number:
2.13.0
The following are the changes in this release:
For historical purposes, in lucas.cal, gen_v1(1, n) always returns 4.
Fixed some compiler warnings, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Added work around for a gcc warning bug, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Fixed errors in various help files such as:
mat randbit seed srandom types
Removed the MAXSTRING symbol because it was no longer used by calc.
Increased HIST_SIZE (depth of the history stack) from 10k to 32k.
Increased TTYSIZE (reallocation size for terminal buffers) from 100 to 8191.
Increased MAXDEPTH (maximum depth of input stack) from 10 to 255.
Increased interactive input buffer size from 1024 to 256k. This has the
effect of increasing the maximum length of an input line from a tty.
This helps with an interactive bug that was reported by Ruslan Kabatsayev
(b7 dot 10110111 at gmail dot com).
The calc man page indicates that -d also disables the printing of the
leading tilde.
Added information to "help command" about how to silence messages
while reading calc resource files.
Fixed an error message buffer overflow thanks to a report by
Frank Peters <nlp at northernlightsphoto dot biz>.
Replaced all use of the C funcion sprintf() with snprintf().
Replaced all use of the C funcion vsprintf() with vsnprintf().
Replaced all DONT_HAVE_VSPRINTF with DONT_HAVE_VSNPRINTF.
Replaced all Makefile var ${HAVE_VSPRINTF} with ${HAVE_VSNPRINTF}.
