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.
Fixed documentation that referred to the old additive 55
generator. We have been using the subtractive 100 in place
of the additive 55 generator for a while now.
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 constants:
9, 9/10, 10/9, 24, 360, 400
are used by func.c only, so there were moved
from {q,z}math.{c,h} to func.c.
The constants:
3, 4
are used by zrandom.c only, so there were moved
from {q,z}math.{c,h} to zrandom.c.
Improved the way that internal pre-defined constants are managed.
Removed unused internal pre-defined constants. Added code to
prevent an internal pre-defined constant (that was never
allocated) from being freed.
The following are the changes in this release:
Due to issues with clang and Apple Silicon, ARCH_CFLAGS is now,
by default, empty:
ARCH_CFLAGS=
If you want to use, say, -march=native, then either change
the Makefile or make with:
make all ARCH_CFLAGS='-march=native'
Added arch and hardware as GNU Makefile computed values.
As with ${target}, ${arch} and ${hardware} is computed by uname:
target: uname -a
arch: uname -p
hardware: uname -m
Fixed compiling calc on Apple Silicon with homebrew. On Apple
Silicon, HomeBrew installs on into a different location. The
Makefile checks if ${hardware} is arm64 and adjusts the location
of libraries such as readline and history accordingly.
