This updates the cc.darwin* compiler compatibility wrapper scripts
and patches bin/package to identify a 64-bit system, allowing ksh
to build using a simple 'bin/package make' command on at least on
macOS Mojave (10.14.6). Testing on other macOS versions is invited.
src/cmd/INIT/cc.darwin:
- Remove obsolete compatibility cruft
- Update compiler flags:
* remove obsolete/unneeded -DCLK_TCK=100 (this is already defined
in the system header i386/limits.h included by time.h)
* add necessary flags from Apple's Makefile in ksh-27.tar.gz:
-DSHOPT_SPAWN=0 -D_ast_int8_t=int64_t -D_lib_memccpy
source: https://opensource.apple.com/tarballs/ksh/
* add -Wno-unused-value and -Wno-parentheses to suppress excessive
clang warnings that object to David Korn's coding style.
- Update linker flags:
* remove obsolete -Wl,-m
* add flag from Apple's Makefile: -Wl,-search_paths_first
src/cmd/INIT/cc.darwin.i386,
src/cmd/INIT/cc.darwin.i386-64:
- Removed as superfluous (was identical to generic cc.darwin).
bin/package,
src/cmd/INIT/package.sh:
- Fix the recognition of a 64-bit system from the output of a 'file
/bin/sh' command (what an ugly hack... never mind), so that the
architecture is correctly identified as darwin.i386-64.
