Once upon a time it might have been possible to build certain parts of ksh, such as the emacs and vi editors and possibly even the name/value library (nval(3)) as independent libraries. But given the depressing amount of bit rot in the code that we inherited, I am certain that disabling either of these macros had been resulting in a broken build for many years before AT&T abandoned this code base. These are certainly not going to be useful now. Meanwhile the KSHELL macro got in the way of me today, because the Mamfile did not define it for all the .c files, but some headers declared some functionality conditionally upon that macro. So including <io.h> in, e.g., nvdisc.c did not declare the same functions as including that header in files with KSHELL defined. This inconsistency is now gone as well, for various files. I'm currently working on making it possible once again to build libshell as a dynamic library; that should be good enough. And that never involved disabling either of these macros.
