Stefan Eßer 252884ae7e Import new 2-clause BSD licenced implementation of the bc and dc commands 
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.

Makefile
Raw Blame History

# $FreeBSD$
#
# Option file for FreeBSD /usr/src builds.
#
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
# with sensible (usually) defaults.
#
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
# are applicable for that Makefile (typically there are none, but sometimes there
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
# to omit from that make.
#
# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
# variable.
#
# Makefiles may also assume that this file is included by src.opts.mk should it
# need variables defined there prior to the end of the Makefile where
# bsd.{subdir,lib.bin}.mk is traditionally included.
#
# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
# should be added. Old instances should be removed since they were just to
# bridge the gap between FreeBSD 4 and FreeBSD 5.
#
# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
# exception is made for _WITHOUT_SRCONF which turns off this mechanism
# completely inside bsd.*.mk files).
#
.if !target(__<src.opts.mk>__)
__<src.opts.mk>__:
.include <bsd.own.mk>
#
# Define MK_* variables (which are either "yes" or "no") for users
# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
# make(1) environment.
# These should be tested with `== "no"' or `!= "no"' in makefiles.
# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.
#
# These options are used by the src builds. Those listed in
# __DEFAULT_YES_OPTIONS default to 'yes' and will build unless turned
# off. __DEFAULT_NO_OPTIONS will default to 'no' and won't build
# unless turned on. Any options listed in 'BROKEN_OPTIONS' will be
# hard-wired to 'no'. "Broken" here means not working or
# not-appropriate and/or not supported. It doesn't imply something is
# wrong with the code. There's not a single good word for this, so
# BROKEN was selected as the least imperfect one considered at the
# time. Options are added to BROKEN_OPTIONS list on a per-arch basis.
# At this time, there's no provision for mutually incompatible options.
