vendor/bc: upgrade to version 7.1.0

2025-09-11T14:07:46+00:00

This update fixes a few bugs:
- Improper response to double SIGINT with editline.
- Not letting libedit handle terminal size changes.
- A dc crash from improperly handling an error.
- A duplicate check for reference arrays.
- Build failures with GCC 15.

vendor/bc: upgrade to version 6.7.6

2024-07-08T17:49:39+00:00

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

Most files are included in this commit due to a changed date in
the copyright note.

vendor/bc: import version 6.2.4

2023-02-06T21:28:40+00:00

This update contains only documentation changes (new main repository
URL and changed mail address of the program author) and changes to
the build system that do not affect the FreeBSD base system build.

vendor/bc: import version 6.0.2

2022-08-30T18:37:36+00:00

Changes relative to the previous version in FreeBSD:

- Fix error message on certain syntax errors.
- Add digit clamping (build option and run-time option)
- Make -l options no longer overridee scale value set with -S

vendor/bc: imoport release 5.0.0

2021-08-09T20:32:55+00:00

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.

Import new 2-clause BSD licenced implementation of the bc and dc commands

2020-06-27T15:03:19+00:00

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:

- They do not depend on external large number functions (i.e. no dependency
  on OpenSSL or any other large number library)

- They implements all features found in GNU bc/dc (with the exception of
  the forking of sub-processes, which the author of this version considers
  as a security issue).

- They are significantly faster than the current code in base (more than
  2 orders of magnitude in some of my tests, e.g. for 12345^100000).

- They should be fully compatible with all features and the behavior of the
  current implementations in FreeBSD (not formally verified).

- They support POSIX message catalogs and come with localized messages in
  Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
  and Russian.

- They offer very detailed man-pages that provide far more information than
  the current ones.
