-# This workflow is meant for development use and run only on demand.
-# It is customizable to select
-#   - Platforms
-#   - Toolchains
-#   - Branches (no need for core-* prefixes)
-#   - Tests
-# To run the workflow, select "Custom" on the left side in the GH Actions
-# page. Then click the Run workflow button on the right. This will display
-# a dropdown that allows customization as above.
-#
-# To run the workflow, you need to have permissions to the repository.
-# The simplest way is to clone the Tcl mirror on Github. However, that means
-# if you work in fossil, you have a potential 24-hour wait before the mirror
-# updates, which apart from nostalgia about the punched card batch processing
-# era, is not so convenient. My preference instead is to mirror the fossil
-# repository to Github via a local checkout on my system, do the work there
-# pushing to github and running this workflow to verify across platforms
-# and then committing back to the master fossil repository.
-#
-# Improvements to the workflow welcome.

-with focus on changes important to programmers using the Tcl library and
-writing Tcl scripts.
-
-# New commands and options
-
- [New options `-backslashes`, `-commands` and `-variables` for `subst` command](https://core.tcl-lang.org/tips/doc/trunk/tip/712.md)
- [New command `unicode` for Unicode normalization](https://core.tcl-lang.org/tips/doc/trunk/tip/726.md)
- [New `timer` command, switch to monotonic clock and microsecond resolution](https://core.tcl-lang.org/tips/doc/trunk/tip/723.md)
- [Remove `expr` behavior from `lseq`](https://core.tcl-lang.org/tips/doc/trunk/tip/746.md) *Incompatibility*
- [File paths are now treated as case-insensitive on MacOS](https://core.tcl-lang.org/tcl/tktview/e6ca0b1b) *Incompatibility*
- New command `tcl::registry` as a synonym for the `registry` command without needing
-the registry package to be loaded. The registry module is now part of the core
-Tcl DLL in all build configurations.
- [New `lfilter` command for selecting items from a list](https://core.tcl-lang.org/tips/doc/trunk/tip/735.md)
- [Many new functions from C99](https://core.tcl-lang.org/tips/doc/trunk/tip/745.md), specifically: `acosh()`, `asinh()`, `atanh()`, `cbrt()`, `copysign()`, `dim()`,  `erf()`, `erfc()`, `exp2()`, `expm1()`, `fma()`, `gamma()`, `ldexp()`, `lgamma()`, `log1p()`, `log2()`, `logb()`, `nextafter()`, `remainder()`, `signbit()`, and `trunc()`, and (for functions that return multiple values in their C99 API) the commands: `divmod`, `frexp`, `modf`, and `remquo`. (See [this page](https://en.cppreference.com/w/c/numeric/math.html) for more information about these functions; the Tcl functions are _intentionally_ only thin wrappers around the functions in the C99 standard.)
- New `tcltest::configure` option `-iterations` to control number of iterations of each test.
-
-# New public C API
-
- [`Tcl_IsEmpty()` &mdash; checks if the string representation of a value would be the empty string](https://core.tcl-lang.org/tips/doc/trunk/tip/711.md)
- [`Tcl_GetEncodingNameForUser()` &mdash; returns name of encoding from user settings](https://core.tcl-lang.org/tips/doc/trunk/tip/716.md)
- [`Tcl_AttemptCreateHashEntry()` &mdash; version of `Tcl_CreateHashEntry()` that returns NULL instead of panic'ing on memory allocation errors](https://core.tcl-lang.org/tips/doc/trunk/tip/717.md)
- [`Tcl_ListObjRange()`, `Tcl_ListObjRepeat()`, `Tcl_ListObjReverse()` &mdash; C API for new list operations](https://core.tcl-lang.org/tips/doc/trunk/tip/649.md)

+ ****************************************************************************
+ *
+ *  Version 0.1.16.0
+ *
+ *  The ANSI C standard committee, for the C99 standard, specified the
+ *  inclusion of a new standard include file called stdint.h.  This is
+ *  a very useful and long desired include file which contains several
+ *  very precise definitions for integer scalar types that is critically
+ *  important for making several classes of applications portable
+ *  including cryptography, hashing, variable length integer libraries
+ *  and so on.  But for most developers its likely useful just for
+ *  programming sanity.
+ *
+ *  The problem is that some compiler vendors chose to ignore the C99
+ *  standard and some older compilers have no opportunity to be updated.
+ *  Because of this situation, simply including stdint.h in your code
+ *  makes it unportable.
+ *
+ *  So that's what this file is all about.  It's an attempt to build a
+ *  single universal include file that works on as many platforms as
+ *  possible to deliver what stdint.h is supposed to.  Even compilers
+ *  that already come with stdint.h can use this file instead without
+ *  any loss of functionality.  A few things that should be noted about
+ *  this file:
+ *
+ *    1) It is not guaranteed to be portable and/or present an identical
+ *       interface on all platforms.  The extreme variability of the
+ *       ANSI C standard makes this an impossibility right from the
+ *       very get go. Its really only meant to be useful for the vast
+ *       majority of platforms that possess the capability of
+ *       implementing usefully and precisely defined, standard sized
+ *       integer scalars.  Systems which are not intrinsically 2s
+ *       complement may produce invalid constants.
+ *
+ *    2) There is an unavoidable use of non-reserved symbols.
+ *
+ *    3) Other standard include files are invoked.
+ *
+ *    4) This file may come in conflict with future platforms that do
+ *       include stdint.h.  The hope is that one or the other can be
+ *       used with no real difference.
+ *
+ *    5) In the current version, if your platform can't represent
+ *       int32_t, int16_t and int8_t, it just dumps out with a compiler
+ *       error.
+ *
+ *    6) 64 bit integers may or may not be defined.  Test for their
+ *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
+ *       Note that this is different from the C99 specification which
+ *       requires the existence of 64 bit support in the compiler.  If
+ *       this is not defined for your platform, yet it is capable of
+ *       dealing with 64 bits then it is because this file has not yet
+ *       been extended to cover all of your system's capabilities.
+ *
+ *    7) (u)intptr_t may or may not be defined.  Test for its presence
+ *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
+ *       for your platform, then it is because this file has not yet
+ *       been extended to cover all of your system's capabilities, not
+ *       because its optional.
+ *
+ *    8) The following might not been defined even if your platform is
+ *       capable of defining it:
+ *
+ *       WCHAR_MIN
+ *       WCHAR_MAX
+ *       (u)int64_t
+ *       PTRDIFF_MIN
+ *       PTRDIFF_MAX
+ *       (u)intptr_t
+ *
+ *    9) The following have not been defined:
+ *
+ *       WINT_MIN
+ *       WINT_MAX
+ *
+ *   10) The criteria for defining (u)int_least(*)_t isn't clear,
+ *       except for systems which don't have a type that precisely
+ *       defined 8, 16, or 32 bit types (which this include file does
+ *       not support anyways). Default definitions have been given.
+ *
+ *   11) The criteria for defining (u)int_fast(*)_t isn't something I
+ *       would trust to any particular compiler vendor or the ANSI C
+ *       committee.  It is well known that "compatible systems" are
+ *       commonly created that have very different performance
+ *       characteristics from the systems they are compatible with,
+ *       especially those whose vendors make both the compiler and the
+ *       system.  Default definitions have been given, but its strongly
+ *       recommended that users never use these definitions for any
+ *       reason (they do *NOT* deliver any serious guarantee of
+ *       improved performance -- not in this file, nor any vendor's
+ *       stdint.h).
+ *
+ *   12) The following macros:
+ *
+ *       PRINTF_INTMAX_MODIFIER
+ *       PRINTF_INT64_MODIFIER
+ *       PRINTF_INT32_MODIFIER
+ *       PRINTF_INT16_MODIFIER
+ *       PRINTF_LEAST64_MODIFIER
+ *       PRINTF_LEAST32_MODIFIER
+ *       PRINTF_LEAST16_MODIFIER
+ *       PRINTF_INTPTR_MODIFIER
+ *
+ *       are strings which have been defined as the modifiers required
+ *       for the "d", "u" and "x" printf formats to correctly output
+ *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
+ *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
+ *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
+ *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
+ *       defined if INT64_MAX is not defined.  These are an extension
+ *       beyond what C99 specifies must be in stdint.h.
+ *
+ *       In addition, the following macros are defined:
+ *
+ *       PRINTF_INTMAX_HEX_WIDTH
+ *       PRINTF_INT64_HEX_WIDTH
+ *       PRINTF_INT32_HEX_WIDTH
+ *       PRINTF_INT16_HEX_WIDTH
+ *       PRINTF_INT8_HEX_WIDTH
+ *       PRINTF_INTMAX_DEC_WIDTH
+ *       PRINTF_INT64_DEC_WIDTH
+ *       PRINTF_INT32_DEC_WIDTH
+ *       PRINTF_INT16_DEC_WIDTH
+ *       PRINTF_UINT8_DEC_WIDTH
+ *       PRINTF_UINTMAX_DEC_WIDTH
+ *       PRINTF_UINT64_DEC_WIDTH
+ *       PRINTF_UINT32_DEC_WIDTH
+ *       PRINTF_UINT16_DEC_WIDTH
+ *       PRINTF_UINT8_DEC_WIDTH
+ *
+ *       Which specifies the maximum number of characters required to
+ *       print the number of that type in either hexadecimal or decimal.
+ *       These are an extension beyond what C99 specifies must be in
+ *       stdint.h.
+ *
+ *  Compilers tested (all with 0 warnings at their highest respective
+ *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
+ *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
+ *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
+ *
+ *  This file should be considered a work in progress.  Suggestions for
+ *  improvements, especially those which increase coverage are strongly
+ *  encouraged.

-    find_package(minizip CONFIG COMPONENTS shared static REQUIRED)
-
-As it's possible to only build the shared or the static lib, you can make sure that everything you need
-is found. If no COMPONENTS are requested, everything needs to be found to satisfy your request. If the
-libraries are optional in you project, you can omit the REQUIRED and check yourself if the targets you
-want to link against are created.

+This is a patched version of zlib, modified to use
+Pentium-Pro-optimized assembly code in the deflation algorithm. The
+files changed/added by this patch are:
+
+README.686
+match.S
+
+The speedup that this patch provides varies, depending on whether the
+compiler used to build the original version of zlib falls afoul of the
+PPro's speed traps. My own tests show a speedup of around 10-20% at
+the default compression level, and 20-30% using -9, against a version
+compiled using gcc 2.7.2.3. Your mileage may vary.
+
+Note that this code has been tailored for the PPro/PII in particular,
+and will not perform particuarly well on a Pentium.
+
+If you are using an assembler other than GNU as, you will have to
+translate match.S to use your assembler's syntax. (Have fun.)
+
+Brian Raiter
+breadbox@muppetlabs.com
+April, 1998
+
+
+Added for zlib 1.1.3:
+
+The patches come from
+http://www.muppetlabs.com/~breadbox/software/assembly.html
+
+To compile zlib with this asm file, copy match.S to the zlib directory
+then do:
+
+CFLAGS="-O3 -DASMV" ./configure
+make OBJA=match.o
+
+
+Update:
+
+I've been ignoring these assembly routines for years, believing that
+gcc's generated code had caught up with it sometime around gcc 2.95
+and the major rearchitecting of the Pentium 4. However, I recently
+learned that, despite what I believed, this code still has some life
+in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
+faster than the code produced by gcc 4.1.
+
+In acknowledgement of its continuing usefulness, I've altered the
+license to match that of the rest of zlib. Share and Enjoy!
