Subject: [PATCH 03/42] Significantly refactor fatal error handling

Because new glibc has changed `MINSIGSTKSZ` to be a syscall instead
of being constant, the signal posix handling needed changes, as it
used the value in constexpr context, for deciding size of an array.
It would be simple to fix it by having the handler determine the
signal handling stack size and allocate the memory every time the
handler is being installed, but that would add another allocation
and a syscall every time a test case is entered.

Instead, I split apart the idea of preparing fatal error handlers,
and engaging them, so that the memory can be allocated only once
and still be guarded by RAII.

Also turns out that Catch2's use of `MINSIGSTKSZ` was wrong, and
we should've been using `SIGSTKSZ` the whole time, which we use now.

Closes #2178

Subject: [PATCH 05/42] Don't build Catch2WithMain target by default for v2

The `Catch2WithMain` target was added experimentally for v2.13.4
to provide potentially better compilation (and link) times to users.
However, having it compiled by default causes worse experience for
people who do not use it, and for the v2 versions the single include
distribution is still the main one.

Closes #2142

+
+### Improvements
+* Detection of MAC and IPHONE platforms has been improved (#2140, #2157)
+* Added workaround for bug in XLC 16.1.0.1 (#2155)
+* Add detection for LCC when it is masquerading as GCC (#2199)
+* Modified posix signal handling so it supports newer libcs (#2178)
+  * `MINSIGSTKSZ` was no longer usable in constexpr context.
+
+### Fixes
+* Fixed compilation of benchmarking when `min` and `max` macros are defined (#2159)
+  * Including `windows.h` without `NOMINMAX` remains a really bad idea, don't do it
+
+### Miscellaneous
+* `Catch2WithMain` target (static library) is no longer built by default (#2142)
+  * Building it by default was at best unnecessary overhead for people not using it, and at worst it caused trouble with install paths
+  * To have it built, set CMake option `CATCH_BUILD_STATIC_LIBRARY` to `ON`
+* The check whether Catch2 is being built as a subproject is now more reliable (#2202, #2204)
+  * The problem was that if the variable name used internally was defined the project including Catch2 as subproject, it would not be properly overwritten for Catch2's CMake.

Subject: [PATCH 14/42] JUnit reporter uses only 3 decimal places when
 reporting durations

We used to use whatever precision we ended up having from C++'s
stdlib. However, some relatively popular tools, like Jenkins,
use Maven SureFire XML schema to validate JUnit test reports, and
Maven SureFire schema requires the duration to have at most 3
decimal places.

For compatibility, the JUnit reporter will now respect this
limitation.

Closes #2221

Subject: [PATCH 20/42] Fix warning suppressions leaking under clang.exe

When running clang.exe under Windows, catch.hpp leaks warning
suppressions because it uses `#pragma warning(push)` & `#pragma
warning(pop)` around warning suppressions like `#pragma clang diagnostic
ignore "-Wunused-variable"`, instead of using `#pragma clang diagnostic
push` and `#pragma clang diagnostic pop`.

This fixes that by only defining
`CATCH_INTERNAL_START_WARNINGS_SUPPRESSION` and
`CATCH_INTERNAL_STOP_WARNINGS_SUPPRESSION` to be the cl.exe variants if
`defined(_MSC_VER) && !defined(__clang__)`.

 This section outlines known bugs in 3rd party components (this means compilers, standard libraries, standard runtimes).
 
+### Visual Studio 2015 -- `GENERATE` does not compile if it would deduce char array
+
+VS 2015 refuses to compile `GENERATE` statements that would deduce to a
+char array with known size, e.g. this:
+```cpp
+TEST_CASE("Deducing string lit") {

+A workaround for this is to use the `as` helper and force deduction of

 ### Visual Studio 2017 -- raw string literal in assert fails to compile
 There is a known bug in Visual Studio 2017 (VC 15), that causes compilation error when preprocessor attempts to stringize a raw string literal (`#` preprocessor is applied to it). This snippet is sufficient to trigger the compilation error:

Subject: [PATCH 35/42] ObjectStorage: port away from std::aligned_storage

It's deprecated in C++23. Just use alignas on a char array, wrapped in
a struct to avoid decaying to char*, which is the canonical
implementation of aligned_storage:
https://en.cppreference.com/w/cpp/types/aligned_storage#Possible_implementation

Fixes #2419

Catch3 is not affected.

Subject: [PATCH 36/42] Use better instruction for CATCH_TRAP on ARM Macs

The old instruction would cause the debugger to be stuck at the
triggering source line forever, while the new one should have the
expected semantics, where the debugger can then single-step,
continue. or generally do things, afterwards.

Closes #2422
