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. The upstream sources contain a large number of tests, which are not imported with this commit. They could be integrated into our test framework at a latter time. Installation of this version is controlled by the option "MK_GH_BC=yes". This option will be set to yes by default in 13-CURRENT, but will be off by default in 12-STABLE.
