This update fixes exiting from an interactive bc session with ^D on
FreeBSD and Linux when using editline.
This bug was caused by the macOS fix for editline in version 7.0.0,
which has been reverted in this version.

Building with GCC failed with the following error message:
error: to be safe all intermediate pointers in cast from 'char **'
to 'const char **' must be 'const' qualified [-Werror=cast-qual]
This was caused by main() being declared with "char *argv[]" as the
3rd parameter, but argv later being passed cast to "const char**":
113 | if (BC_IS_BC) s = bc_main(argc, (const char**) argv);
| ^
This is fixed by declaring the 3rd parameter of main() as "const
char *argv[]".

vendor/bc: upgrade to version 7.0.1
This update fixes building bc on FreeBSD with non-default compilers
(GCC-12, GCC-13). GCC warned about casting argv from non-const to const
and since warnings are treated as errors, the build failed.

This is a production release to fix three bugs, none of which
affects well formed scripts on FreeBSD:
The first bug is that bc/dc will exit on macOS when the terminal
is resized.
The second bug is that an array, which should only be a function
parameter, was accepted as part of larger expressions.
The third bug is that the value stack for dc was cleared on any error.
However, this is not how other dc behave. To bring dc more in line
with other implementations, this behavior was changed. This change is
why this version is a new major version.

This update fixes a potential issue when flushing stdout on exit
fails: longjmp could use an uninitialized target address variable.

This is a squashed updated consisting of:
vendor/bc: upgrade to version 6.7.2
This update improves the implementation of the power function p() and
adds 3 new functions to the extended math library: min(), max(), and
i2rand().
(cherry picked from commit aa339f1d5d)
vendor/bc: upgrade to version 6.7.4
Documentation updates only, no functional changes to the software.
(cherry picked from commit e6857bd4d7)
vendor/bc: upgrade to version 6.7.5
This update fixes a bug that line breaks in printed numbers may not
match the line length set by the user. The value is printed correctly,
just not split as specified in some situations.
(cherry picked from commit f4fbc49d20)
This update removes printing of a leading zero in scientific or
engineering output modes (which are an extended feature of this
implementation).

This release that fixes an infinite loop bug in the (non-standard)
extended math library functions root() and cbrt(), fixes a bug with
BC_LINE_LENGTH=0, and adds the fib() function to the extended math
library to calculate Fibonacci numbers.

This version contains a fix for an issue that can affect complex

an interactive user. The same value could be returned multiple times.

URL and changed mail address of the program author) and changes to

This update fixes a few issues in history editing and the processing
of the "quit" function. The "quit" function will no longer cause bc
to exit when encountered in a script file (before any command from
the script has been executed).
New functions is_number(), is_string return 1 if the passed argument
is a number resp. a string. The asciify() function has been extended
to support the conversion of an array of numbers into a string.

This version adds support for command line editing and history using
the libedit or readline libraries in addition to the line editing
features available in previous versions.
The version in the base system is configured to use libedit.
This allows to choose between emacs and vi line editing commands and
to use command overrides via a ~/.editrc file.

This release assigns a default value to the internal program name
variable in case the program is invoked with argv[0] == NULL.
There was no security issue: the prevuous program version would have
been immediately terminated due to a NULL dereference.
This version adds options and functions that allow to print numbers
in the open interval (-1 .. 1) with or without a leading 0 digit.
Additionally, an option has been added to prevent line wrap and
allows to print arbitrarily long results on a single line.

This is a new major release with a number of changes and extensions:
- Limited the number of temporary numbers and made the space for them
static so that allocating more space for them cannot fail.
- Allowed integers with non-zero scale to be used with power, places,
and shift operators.
- Added greatest common divisor and least common multiple to lib2.bc.
- Made bc and dc UTF-8 capable.
- Added the ability for users to have bc and dc quit on SIGINT.
- Added the ability for users to disable prompt and TTY mode by
environment variables.
- Added the ability for users to redefine keywords.
- Added dc's modular exponentiation and divmod to bc.
- Added the ability to assign strings to variables and array elements
and pass them to functions in bc.
- Added dc's asciify command and stream printing to bc.
- Added bitwise and, or, xor, left shift, right shift, reverse,
left rotate, right rotate, and mod functions to lib2.bc.
- Added the functions s2u(x) and s2un(x,n), to lib2.bc.

This update fixes the initialization of "scale" to 20 if started with
-l and the initial statement leads to an error (e.g. contains a syntax
error). Scale was initialized to 0 in that case.
Another change is the support of job control in interactive mode with
line editing enabled. The control characters have been interpreted as
editing commands only, prior to this version.

Update to version 4.0.0
This version fixes an issue (missing pop of top-of-stack value in the
"P" command of the dc program).
This issue did not affect the bc program, since it does not use dc as
an back-end to actually perform the calculations as was the case with
the traditional bc and dc programs.
The major number has been bumped due to Windows support that has been
added to this version. It does not correspond to a major change that
might affect FreeBSD.
