Get rid of overcomplicated AT&T copyright/license maintenance code
I'm now taking another small step towards extricating this build
system from the long-dead AT&T AST universe.
This commit modifies/reduces the tool called proto. AT&T used proto
for two purposes:
1. To convert ANSI C code to a form compatible with ancient
(pre-ANSI) K&R C compilers using extremely complex macro
voodo. It was similarly capable of translating to C++.
Theoretically, this entire code base should compile on
anything from a 1980s K&R C compiler to a modern C++ compiler.
In practice, given the massive amount of bit rot we inherited,
I am 99.9% sure that this has been broken for many years.
2. To automagically insert license comments into source files
based on an extremely complicated license database system.
(In all-too-typical AT&T fashion, this second function of
proto is completely unrelated to the first.)
Function 2 has now been removed because, unlike the AT&T legal
department, I don't think it's worth going to unspeakably extreme
lengths to avoid maintaining license information in source code
files by hand.
In the process, proto.c was cleaned up to look halfway like actual
C code, but it's still processed code: most macros have been
expanded to their numeric value, all comments were stripped, etc.
So don't expect to understand this code. The actual source code is
in these two directories in the ast-open-history repo:
https://github.com/ksh93/ast-open-history/tree/master/src/cmd/proto
https://github.com/ksh93/ast-open-history/tree/master/src/lib/libpp
Meanwhile, nobody wants to compile ksh with a pre-ANSI K&R C
compiler in 2021 -- and there's no good reason to be compatible
with C++ because standard C compilers are universally available.
So, proto will go away when I manage to figure out how to pry it
loose from the innards of this build system.
src/lib/libast/port/astlicense.c:
- Removed. This is al the license handling code that was
incorporated in proto.c in stripped form. It was not used
anywhere else, and the environment where it was useful is gone.
src/cmd/INIT/proto.c:
- Cleanup to make this halfway maintainable: indentation, huge
blocks of empty lines, #line directives, etc.
- Delete all the code corresponding to astlicense.c. This was
actually easy as it was in a discrete block.
- proto(), pppopen(): Remove 'license'/'notice' and 'options'
arguments.
- main(): Remove processing of -l (license) and -o (license
options) flags.
**/Mamfile:
- Update all the proto invocations to remove the -l and -o flags.
bin/package, src/cmd/INIT/package.sh:
- Delete the 'copyright' command, which used the -l and -o
options to tell proto to extract copyright information from
*.lic/*.def files in lib/package.
COPYRIGHT:
- Added. This has the information from 'bin/package copyright', with
the copyright years corrected to plausible values as the AST code
used the current year (2021) for all of them. It adds ksh 93u+m
copyright and contributor information at the top as well.
(Yes, some of the lines in the old non-AT&T copyright notices
are clipped. This is the actual output of the 'bin/package
copyright' command as generated by 'proto' in the AST
distribution. For all that extreme complexity, they couldn't even
reproduce the notices correctly. But it's officially sanctioned
by AT&T in exactly this form, so there you have it.)
lib/package/**:
- Removed. All these files are now obsolete and redundant.

# The KornShell 93u+m distribution #

Another round of accumulated tweaks and cleanups
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.

- proto(), pppopen(): Remove 'license'/'notice' and 'options'
arguments.
- main(): Remove processing of -l (license) and -o (license
options) flags.
**/Mamfile:
- Update all the proto invocations to remove the -l and -o flags.
bin/package, src/cmd/INIT/package.sh:
- Delete the 'copyright' command, which used the -l and -o
options to tell proto to extract copyright information from
*.lic/*.def files in lib/package.
COPYRIGHT:
- Added. This has the information from 'bin/package copyright', with
the copyright years corrected to plausible values as the AST code
used the current year (2021) for all of them. It adds ksh 93u+m
copyright and contributor information at the top as well.
(Yes, some of the lines in the old non-AT&T copyright notices
are clipped. This is the actual output of the 'bin/package
copyright' command as generated by 'proto' in the AST
distribution. For all that extreme complexity, they couldn't even
reproduce the notices correctly. But it's officially sanctioned
by AT&T in exactly this form, so there you have it.)
lib/package/**:
- Removed. All these files are now obsolete and redundant.

Another round of accumulated tweaks and cleanups
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.

Get rid of overcomplicated AT&T copyright/license maintenance code
I'm now taking another small step towards extricating this build
system from the long-dead AT&T AST universe.
This commit modifies/reduces the tool called proto. AT&T used proto
for two purposes:
1. To convert ANSI C code to a form compatible with ancient
(pre-ANSI) K&R C compilers using extremely complex macro
voodo. It was similarly capable of translating to C++.
Theoretically, this entire code base should compile on
anything from a 1980s K&R C compiler to a modern C++ compiler.
In practice, given the massive amount of bit rot we inherited,
I am 99.9% sure that this has been broken for many years.
2. To automagically insert license comments into source files
based on an extremely complicated license database system.
(In all-too-typical AT&T fashion, this second function of
proto is completely unrelated to the first.)
Function 2 has now been removed because, unlike the AT&T legal
department, I don't think it's worth going to unspeakably extreme
lengths to avoid maintaining license information in source code
files by hand.
In the process, proto.c was cleaned up to look halfway like actual
C code, but it's still processed code: most macros have been
expanded to their numeric value, all comments were stripped, etc.
So don't expect to understand this code. The actual source code is
in these two directories in the ast-open-history repo:
https://github.com/ksh93/ast-open-history/tree/master/src/cmd/proto
https://github.com/ksh93/ast-open-history/tree/master/src/lib/libpp
Meanwhile, nobody wants to compile ksh with a pre-ANSI K&R C
compiler in 2021 -- and there's no good reason to be compatible
with C++ because standard C compilers are universally available.
So, proto will go away when I manage to figure out how to pry it
loose from the innards of this build system.
src/lib/libast/port/astlicense.c:
- Removed. This is al the license handling code that was
incorporated in proto.c in stripped form. It was not used
anywhere else, and the environment where it was useful is gone.
src/cmd/INIT/proto.c:
- Cleanup to make this halfway maintainable: indentation, huge
blocks of empty lines, #line directives, etc.
- Delete all the code corresponding to astlicense.c. This was
actually easy as it was in a discrete block.
- proto(), pppopen(): Remove 'license'/'notice' and 'options'
arguments.
- main(): Remove processing of -l (license) and -o (license
options) flags.
**/Mamfile:
- Update all the proto invocations to remove the -l and -o flags.
bin/package, src/cmd/INIT/package.sh:
- Delete the 'copyright' command, which used the -l and -o
options to tell proto to extract copyright information from
*.lic/*.def files in lib/package.
COPYRIGHT:
- Added. This has the information from 'bin/package copyright', with
the copyright years corrected to plausible values as the AST code
used the current year (2021) for all of them. It adds ksh 93u+m
copyright and contributor information at the top as well.
(Yes, some of the lines in the old non-AT&T copyright notices
are clipped. This is the actual output of the 'bin/package
copyright' command as generated by 'proto' in the AST
distribution. For all that extreme complexity, they couldn't even
reproduce the notices correctly. But it's officially sanctioned
by AT&T in exactly this form, so there you have it.)
