Notable changes: - Remove SHOPT_PFSH compile-time option and associated code. This was meant to work with Solaris rights profiles, see: https://docs.oracle.com/cd/E23824_01/html/821-1461/profiles-1.html#REFMAN1profiles-1 But it has been obsolete for years as Solaris stopped using it in its shipped ksh several OS versions ago, preferring a library-based wrapper around ksh and other shells. Nonetheless I experimented with the option on Solaris 11.4. Result: no external command will run; output of unitialised memory in error message. So it's already fallen victim to bit rot. There's nothing interesting here, so just get rid. - Remove SHOPT_TYPEDEF compile-time option (but keep the code!). Turning it off caused the build to fail. It may be possible to fix it, but the type definition code is integral to ksh now (e.g. 'enum' depends on much of it) so it makes no sense to disable it. This was removed in the ksh 93v- beta version as well. - Remove nv_close() calls and remove nv_close() documentation from the nval.3 man page. This function is a dummy, present without any changes since the beginning of the ast-open-archive repo in 1995. The comment was: "Currently this is a dummy, but someday will be needed for reference counting". 27 or more years later, it's time to admit it's never going to happen. (And of course, nv_close() calls were not being used with anything resembling consistency.) - Add a null nv_close() macro to nval.h for compatibility with third party code that follows the old documentation. - Add a few missing regression tests.
