Notable changes:
src/cmd/ksh93/*.c:
- Get rid of all the dtuserdata(FOO,&sh,1) calls backported in
cc492752. These set pointers to sh in Cdt objects. As of
b590a9f1, the code does not use any pointers to sh, so these are
superfluous.
src/cmd/ksh93/data/builtins.c,
src/cmd/ksh93/sh.1:
- As of ksh 93l 2001-06-01, the -h/trackall option has no effect at
all, so trim its documentation.
src/lib/libast/man/stk.3,
src/lib/libast/man/stak.3:
- Correct the documentation on what the ST(A)K_SMALL option bit
actually does based on a reading of the code.
- Document the STK_NULL option bit.
README.md,
src/cmd/ksh93/README:
- Add a note that -fdiagnostics-color=always will break the build.
Ref.: https://github.com/ksh93/ksh/issues/379
src/lib/libast/Mamfile:
- Remove a 'rm -f astmath' command -- a file that is never created.
But on Cygwin this removes astmath.exe, which *is* used. As a
result, executing it failed on Cygwin, so the system incorrectly
detected that Cygwin needs -lm for math functions.
