CHECKPOINT: The complete AST suite now builds without error on generic UnixWare 7.1.4. * src/cmd/ss/Makefile: Properly handle sys ownership of /dev/kmem. * src/cmd/ss/Mamfile: Regenerate Mamfile. * src/lib/libast/features/standards: - Add heuristic (u_long availability) for systems that hide rather than reveal functionality in the presence of _POSIX_SOURCE, etc. - Define _DARWIN_C_SOURCE, like _GNU_SOURCE, to enable the full range of definitions on Mac OS X systems. - Due to the above, remove __MACH__ (Mac OS X)-specific hack.

Hi, I'm not sure why you bothered to post a PR here as this repo is inactive and AT&T will ignore it, but I'm glad you did, because the libast bit of this is applicable to ksh 93u+m. :-) |

src/lib/libast/features/standards: - Add heuristic (u_long availability) for systems that hide rather than reveal functionality in the presence of _POSIX_SOURCE, etc. - Define _DARWIN_C_SOURCE, like _GNU_SOURCE, to enable the full range of definitions on macOS systems. - Due to the above, remove MACH (macOS)-specific hack. - These changes ported from att#1492 - thanks to Lev Kujawski (@lkujaw). His PR indicates that this fixes the standards macros on UnixWare, too. Therefore, no longer exclude UnixWare from standards macros (re: ff70c27). src/lib/libast/comp/conf.sh: - Promote the 'op' member in Conf_t (struct Conf_s) from short to int. This allows some Darwin/macOS values, now exposed, to fit that would otherwise be truncated, namely: _CS_DARWIN_USER_CACHE_DIR 65538 _CS_DARWIN_USER_DIR 65536 _CS_DARWIN_USER_TEMP_DIR 65537 Thus, the following AST getconf values are now correct on macOS: $ /opt/ast/bin/getconf | grep ^DARWIN DARWIN_USER_CACHE_DIR=/var/folders/nx/(REDACTED)/C/ DARWIN_USER_DIR=/var/folders/nx/(REDACTED)/0/ DARWIN_USER_TEMP_DIR=/var/folders/nx/(REDACTED)/T/ src/lib/libast/features/tty: - Include <sys/ioctl.h> if available. This silences a compiler warning in src/lib/libast/misc/procopen.c about an invalid implicit declaration of ioctl(2).
