The following are the changes from calc version 2.14.0.9 to date:
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.
The following are the changes from calc version 2.14.0.7 to 2.14.0.8:
Fizzbin is a better word. :-)
